Abstract :
To address the limitations of conventional powdered catalytic materials, including difficulty of recycling, low catalytic activity, and limited applicability to different pollutants, this study developed a wood-based@InCoOS composite catalytic materials with rapid recycling characteristics and suitable for the catalytic reduction of various pollutants. By employing bimetallic oxysulfide in situ decoration, the wood was successfully endowed with catalytic functionality, and the catalytic activities of poplar wood-based (PT@InCoOS) and Chinese fir wood-based (CF@InCoOS) composite catalytic materials were compared across multiple pollutants. The results revealed that both PT@InCoOS and CF@InCoOS showed excellent catalytic reduction performance, but with significant differences. PT@InCoOS achieved complete reduction of new coccine (NC), methylene blue (MB), and rhodamine B (RhB) within 3, 3, and 20 min, respectively, and completely reduced Cr(VI) and p-nitrophenol (4NP) within 22 and 20 min. In contrast, CF@InCoOS required 5, 4, 24, 32, and 30 min for the same pollutants. PT@InCoOS exhibited superior performance due to its higher electron transferring capability and favorable bandgap structure, while the interfacial synergistic effect effectively promoted the photogenerated carrier transport and utilization efficiency. Even after six cycles of use, wood-based@InCoOS composite catalytic materials retained over 88 % of their catalytic efficiency, demonstrating excellent reusability. The materials have low cost, high activity, easy recycling, and environmental friendliness and demonstrate great potential as a microreactor in environmental remediation.

Abstract :
Environment and energy are presently some of the highest priority topics for mankind that need to be addressed. Organic pollutants are toxic and carcinogenic for human and aquatic life hence their presence in water even in low concentrations can cause serious health problems. Photodegradation of organic pollutants by utilizing oxidebased heterostructure photocatalysts is the promising approach to carry out remediation efficiently ascribed to the advanced optoelectronic and structural superiority of oxide photocatalysts. The Zn(O,S)/Mo(O,S)2 composites were synthesized via a facile solvothermal method at low temperatures. Several methods were used to characterize the composite morphology, structure, electrical conductivity, chemical composition, and optical characteristics. The heterostructured Zn(O,S)/Mo(O,S)2 oxysulfide was employed successfully in the photocatalytic degradation of organic pollutants. Among the as-prepared samples, the 30-ZnMoOS composite catalyst was found to have the highest photodegradation performance on various organic dye pollutants. The photocatalytic activity of the as-synthesized Zn(O,S)/Mo(O,S)2 samples was assessed on the photodegradation of different kinds of organic dyes under visible light irradiation. The photocatalytic degradation efficiency of 30ZnMoOS composite over 10 ppm neutral red (NR), methylene blue (MB), rhodamine B (Rh B), and methyl orange (MO) was found to be 99.6%, 99.9%, 99.5%, and 98.8% within 40, 45, 180, and 180 min, respectively, under visible light illumination. In the present photocatalytic system, the superoxide ( . O 2- ) anions, hydroxyl (.OH) radicals, and holes (h+) are proposed to be the direct reactive species causing the photodegradation of organic dyes.

Abstract :
While bismuth oxychloride is a known photocatalyst, its single-phase form for photocatalytic hydrogen evolution (PHER) has rarely been explored. This paper presents a novel approach to the 'braided-channel' structured and superhydrophilic Mn/S co-doped BiOCl-based bimetal sulfur-oxychloride catalyst (Mn/S-BiOCl). With its enriched oxygen-vacancy defect and heterovalent states, this catalyst demonstrates efficient PHER under visible light. The Mn/S co-doping in BiOCl adjusts the band structure and expands the visible light response range, a unique strategy for forming photocatalysts for hydrogen evolution and transforming hydrophobicity into superhydrophilicity. The introduction of sulfur regulates the oxygen-vacancy contents to enhance water molecule trapping on active sites and activating H-O-H bonds. Our density functional theory (DFT) calculation reveals that Mn/S co-doped BiOCl with oxygen vacancy (Vo) defects weakens the H-O-H bond and reduces the reaction adsorption energy of H2O, resulting in high selectivity. In addition, heterovalent Mn2+/Mn3+ and Bi3+/Bi5+ are conducive to the accelerated electron jump, extended electron lifetime, and elevated PHER activity. The Mn/SBiOCl-3 prepared with a suitable Mn/S co-doping content exhibited the highest PHER rate of 607.5 mu mol & sdot;h-1 under visible light, with an apparent quantum efficiency (AQE) of 11.6 % at 420 nm. This successful design in Mn/S-BiOCl with excellent PHER activity, stability, and durability provides a novel and feasible idea and scheme for applying bismuth-based halide oxides in PHER.

Abstract :
To reveal the role of bi-vacancy defects and heterovalent states in oxysulfide catalysts for enhancing the photocatalytic hydrogen evolution reaction (PHER), we demonstrate a Br/W co-doped Zn(O,S) catalyst (labeled as Br/W-ZnOS) featuring abundant anionic oxygen vacancies (VO)/cationic zinc vacancies (VZn) bi-defects and heterovalent W5+/W6+ states via a facile hydrolysis method. The co-doping of Br and W induces lattice distortions that enable neighboring atoms to leave the lattice, creating surfaces enriched with anionic VO and cationic VZn defects. The synergistic effect between dual defects forms an efficient electron-hole separation system, enhancing the efficiency of electron-hole pair separation. Density functional theory calculation (DFT) demonstrates that the combination of Br/W co-doping and vacancies significantly reduces the water dissociation barrier and optimizes the surface *H generation rate of the photocatalyst. Thus, Br/W-ZnOS exhibits a PHER rate of 3415.7 mu mol h- 1, which is 12.5 times higher than the undoped Zn(O,S) catalyst, and achieves an apparent quantum yield (AQY) of 15.41 % at 365 nm, while maintaining good stability with a PHER activity of 3288.1 mu mol h- 1 after five repeated cycles. This research provides a promising strategy for designing oxysulfide catalysts with synergistically engineered defects for efficient PHER.

Abstract :
A Co/O co-doped ZnS-based bimetal oxysulfide (labeled as ZnCoOS) with heterovalent Co2+/Co3+ states and rich sulfur vacancies (Vs) defects was designed via a facile method for photocatalytic hydrogen evolution reaction (PHER). ZnCoOS possesses excellent electrical conductivity and electron trapping capacity, providing more reactive active sites. Introducing Co-/O- to regulate ZnCoOS with abundant Vs defects acts as active sites to trap H2O molecules and activate H-O-H bonds, producing protons for H2 production. Hydrogen peroxide regulated ZnCoOS, offering suitable heterovalent Co2+/Co3+ states and providing sites for photogenerated electrons to rapidly hop between Co2+ and Co3+ for charge transfer during PHER. The ZnCoOS-3 with optimal hydrogen peroxide regulation achieved an excellent PHER rate of 2180 mu mol h- 1 and AQE of 19.11% at 365 nm, approximately 8 times higher than monometallic ZnOS and 5.5 times higher than ZnCoOS prepared without H2O2. Furthermore, ZnCoOS had good photocatalytic stability and durability. A rational mechanism to enhance PHER activity was also explored, providing new insights into the design and application of ZnCoOS bimetal oxysulfide for PHER.

Abstract :
Herein, we designed a stable and photocorrosion-resistant Mo/O co-doped ZnS (labeled as ZnMoOS) catalyst with abundant sulfur vacancy (Vs) defects and bivalent Mo4+/Mo6+ states for an effective photocatalytic hydrogen evolution reaction (photo-HER) under visible light. The Mo/O co-doping reduces the band gap of ZnS and extends its visible light absorption range. The hydrazine-driven process adjusts ZnMoOS with appropriate bivalent n(Mo4+)/n(Mo6+) states and creates abundant Vs defects. The Vs defects are active sites to capture water molecules and weaken H-O-H bonds for producing protons and H2 generation. The bivalent n(Mo4+)/n(Mo6+) states act as hosts for photogenerated electrons, facilitating the rapid hopping of photogenerated electrons between Mo4+ <-> Mo6+ to transfer for the photo-HER, thereby improving the photo-HER efficiency. DFT calculations reveal that Mo/O co-doping of ZnMoOS with abundant Vs defects and heterovalent Mo4+/Mo6+ states significantly facilitates hydrogen desorption and enhances the surface H* generation rate. ZnMoOS-3 with appropriate Mo/O co-doping and regulation with an optimum hydrazine content exhibits an excellent photo-HER rate of 41.6 mmol g-1 h-1 and an AQE of 18.6% at 400 nm, along with good durability and stability. This work provides a strategy for vacancy defects and heterovalent states for designing sulfide catalysts with high photo-HER activity and inhibition of photocorrosion.

Abstract :
Developing sustainable and economically viable methods is paramount to mitigate the harmful effects of dyes and conserve water resources. This study used the hydrothermal method to effectively synthesize an In2S3/Bi2S3/ BiOBr heterojunction catalyst. The electrochemical properties of the In2S3/Bi2S3/BiOBr were enhanced by the presence of heterovalent In3+ and Bi3+ oxidation states, which facilitated electron transport and pollutant degradation. The heterojunction catalyst synthesized from prefabricated BiOBr, Bi2S3, and In2S3 showed the most pronounced catalytic activity. Its catalytic effectiveness was studied for the degradation of methylene blue (MB), methyl orange (MO), and rhodamine B (RhB), achieving efficiencies of 95.3 %, 99.5 %, and 98.3 % within 120, 100, and 100 min, respectively, in 50 ppm 100 mL of each dye at 10 mg of In2S3/Bi2S3/BiOBr. The In2S3/Bi2S3/ BiOBr featured remarkable stability and efficiency, maintaining a degradation rate of 95.8 % even after five runs. The e- /h + transitions occurring between BiOBr, Bi2S3, and In2S3 led to an enhancement of the electrochemically active surface sites and thereby optimized the catalytic activity. The ability of the In2S3/Bi2S3/BiOBr to absorb visible light led to generating reactive species such as center dot O 2- and h+ free radicals, which were crucial for the degradation of MB, MO, and RhB. These results highlight the exceptional catalytic potential of the In2S3/Bi2S3/ BiOBr heterojunction for the degradation of chemical pollutants, thereby providing a sustainable and effective solution for environmental remediation.

Abstract :
A novel AgVOS oxysulfide catalyst for rapid catalytic reduction of toxic organic substances and Cr(VI) under dark is synthesized by a facile method. With the V/O co-doping, the doped Ag2S catalyst has the effectively regulated electron transfer performance, the hydrazine-driven V5+-to-V4+ reduction to disturb charge equilibrium, and the formed sulfur vacancy balanced by oxygen doping to maintain charge equilibrium. The formed sulfur vacancy acts as the active site for electrophilic nucleophilic reaction, while the orbital hybridization of O-2p and S-3p stabilizes the valence state of S2-. A suitable ratio of n(V4+/V5+) is regulated during the hydrazine-driven synthesis to facilitate the electron transfer and enhance the V5+-to-V4+ reduction reaction. V/O co-doped AgVOS-3 prepared by a suitable hydrazine content exhibits super catalytic reduction performance of organic 4-NP (4-nitrophenol), MB (methyl blue), MO (methyl orange), and RhB (Rhodamine B, 20 ppm, 100 mL) dyes, which are completely reduced within 8, 8, 10, and 8 min, respectively. In comparison, Cr6+ (50 ppm, 100 mL) is also completely reduced within 6 min by AgVOS-3, indicating its good catalytic reduction activity for organic and inorganic mixture pollutants. Furthermore, AgVOS-3 has good stability after cyclic tests to maintain a reduction efficiency of 96.5%. Therefore, the AgVOS catalyst shows a promising application for industrial wastewater treatment.

Abstract :
In this paper, cellulose-supported SnW(S,O)4 bimetal sulfo-oxide catalysts (labeled as SnWSO-C or SW@C) with exceptional catalytic performance in the reduction of MB, RhB, and Cr(VI) in the presence of NaBH4 under dark conditions were synthesized via an in-situ hydrolysis method. The cellulose-supported catalyst system with diverse tree species of Pinus massoniana (Pm), Populus tomentosa Carri & egrave;re (Ptc), Rice hull (Rh), Phyllostachys edulis (Pe) was investigated. The 100 mL solutions of MB (20 ppm), RhB (50 ppm), and Cr(VI) (50 ppm) were completely reduced by SW@Cotton, SW@Pe, SW@Rh, SW@Ptc, and SW@Pm within 10, 7, 13, 4, and 4 min for MB; 7, 7, 8, 10, and 4 min for RhB; and 5, 8, 10, 10, and 8 min for Cr(VI), respectively. Among them, SW@Pe catalyst exhibits the highest catalytic reduction efficiency and excellent stability, maintaining a removal rate of 96% after six cycles. The superior catalytic reduction performance was attributed the unique properties of Phyllostachys edulis cellulose, characterized by low crystallinity (53.25%), minimal ash content (0.15%), and the lowest degree of polymerization (1267). These features facilitated the improved dispersion of the SnWSO bimetal sulfo-oxide, leading to smaller crystal size, lower electrochemical impedance (2.24 Omega), and a larger electrochemically active surface area (21.86 mF/cm(2)). This study demonstrates the potential of cellulose-supported bimetal sulfo-oxide catalysts for wastewater treatment, which is significant for advancing future research on environmental pollution management using biomass-based materials.

Abstract :
Lignin, a negatively charged, three-dimensional natural biopolymer, serves as an ideal support for metal catalysts due to its abundant functional groups and tunable chemical properties, which enable strong metal coordination and effective immobilization. Herein, we demonstrate a lignin-mediated Co/O co-doped Ag2S, symbolized as LAgCoOS, bimetal oxysulfide catalyst via a facile hydrolysis method for the efficient reduction of toxic phenolic compounds (4-nitrophenol, 4-NP), organic dyes (methyl orange (MO), methylene blue (MB), rhodamine B (RhB), and heavy metal ions Cr(VI)) under dark conditions. Lignin, used to immobilize catalysts, also contributes to increasing the number of active catalytic sites and enhancing catalytic activity. The co-doping of transition metal cations and anions was employed to effectively regulate the electron transfer property of the catalyst, with oxygen doping modifying the energy band structure and cobalt providing heterovalent Co3+/Co2+ states that facilitate rapid electron hopping between Co2+ and Co3+ (Co2+ <-> Co3+) to transfer for catalytic reduction of pollutants. Furthermore, the hybridization of O 2p and S 3p orbitals improved the structural stability of the catalyst. L-AgCoOS with an appropriate level of cobalt doping exhibited significantly enhanced catalytic reduction efficiency. Specifically, 5 mg of L-AgCoOS-2 could completely reduce 100 ml of 20 ppm 4-NP within 8 min, with the reaction rate constant of 0.26 min-1. Additionally, it achieved a complete reduction of 100 ml of 50 ppm MB, MO, RhB, and Cr(VI) in 4, 3, 4, and 4 min, respectively, with the reaction rate constant of 0.49, 0.51, 0.57, and 0.54 min-1. L-AgCoOS-2 also demonstrated excellent performance in treating mixed pollutants, maintaining high activity across a wide pH range, and good reusability. These results highlight the significant potential of L-AgCoOS-2 for practical applications in wastewater treatment.
