Abstract ：
Microbial biofilm-based hydrovoltaic electricity generators (BioHEGs) have recently been developed as promising and readily available platforms for green energy harvesting, despite their unsatisfactory output performances and unspecified mechanisms regarding electric current production. Herein, carbon quantum dots (CQDs) were used to construct a nano-biohybrid system with Shewanella oneidensis MR-1 (S. oneidensis), through which the CQDs/S. oneidensis BioHEG achieved a maximum open-circuit voltage of ca. 0.65 V and short-circuit current density of ca. 5.23 mu A & sdot;cm-2. In addition, both the hydrovoltaic effect and electrical conductivity of CQDs/S. oneidensis nano-biohybrids were noticeably improved due to enhanced secretion of extracellular polymeric substances (EPS) and accelerated electron transfer upon CQDs implantation, thereby leading to a nearly 14-fold increase in output power density compared to the bare S. oneidensis cells. Studies aimed to elucidate the underlying mechanism indicated that the hybridization of CQDs and S. oneidensis greatly promoted the metabolic synthesis of outer membrane c-type cytochromes (OM c-Cyts) and the extracellular secretion of riboflavin (RF), which was demonstrated to be decisive in the current producing process of the CQDs/ S. oneidensis BioHEG. This work thus proposes a viable strategy to boost the hydrovoltaic electricity generation capacity of microbial biofilms and provides a new perspective on the mechanism of accelerated electron transfer pathways inside BioHEGs.

Abstract ：
The low efficiency of photogenerated charge separation significantly hinders the photocatalytic nitrogen (N2) fixation. Local polarization electric field (LPEF) induced by defects has been known to enhance charge separation, yet the synergistic effects and mechanisms related to different types of defects in pure phases remain poorly understood. In this study, defect-free bismuth oxybromide (BiOBr; BOB), together with single vacancy (BOB-VBr and BOB-VO) and dual vacancy (BOB-VBrO) analogues, were successfully synthesized, and the presence of these specific vacancies was comprehensively characterized. Notably, the dual vacancy BOB-VBrO exhibited the highest photocatalytic NH3 generation rate of 266 mu mol g-1 h-1 in a liquid-solid biphasic system, which was 6.1, 1.5, and 1.4 times higher than those of BOB, BOB-VBr, and BOB-VO, respectively. Furthermore, the NH3 generation capacity of BOB-VBrO reached an impressive rate of 978 mu mol g-1 h-1 in a gas-liquid-solid triphasic system. Photoelectrochemical tests revealed that BOB-VBrO demonstrated the highest light conversion efficiency, followed by BOB-VO, BOB-VBr, and BOB. The relative intensity of the internal electric field in BOB-VBrO was also significantly high, being 1.8, 2.4, and 3.9 times greater than those of BOB-VO, BOB-VBr, and BOB, respectively. The Br and O vacancies synergistically induced LPEF between the [O]/[Br] and [Bi] layers. In situ irradiation X-ray photoelectron spectroscopy indicated that O and Br vacancies of the oligomers could synergistically enhance the LPEF, thereby facilitating the transfer of photogenerated electrons from O/Br to Bi. Additionally, the practical feasibility of BOB-VBrO in photocatalytic N2 fixation was validated to produce liquid nitrogenous fertilizer for plant growth, revealing its potential application in agricultural production.

Abstract ：
In this work, morphological control with a series of sulfur-vacancy-rich CdS photocatalysts has been achieved toward the optimization of their performances in CO2 photoreduction. Results show that sulfur-vacancy-rich CdS nano-platelets (p-CdS-Vs) exhibit the highest CO2 photoreduction activity with a CO yield of 4058.5 mu mol h-1 g-1, which is 10 and 6 times those of sulfur-vacancy-rich CdS nanowires (w-CdS-Vs, 372.8 mu mol h-1 g-1) and nanorods (r-CdS-Vs, 638.7 mu mol h-1 g-1), respectively, amongst the highest numbers for CdS-based photocatalysts reported hitherto. The superior CO2 photoreduction performance of p-CdS-Vs is attributable to its high efficiency of electron transport and suppressed recombination of photogenerated charge carriers. A mechanistic study indicates the critical role of surface sulfur vacancies that provide a microenvironment to trap unpaired electrons for the separation of photogenerated carriers so that the photocatalytic efficiency of CO2-to-CO reduction is largely improved in this current system.

Abstract ：
The viability and sustainability of advanced oxidation processes (AOPs) for the removal of organic pollutants are critically dependent on the catalytic efficiency, environmental compatibility, and reusability of catalysts employed. In this study, we presented a novel recyclable cobalt-incorporated MoS2 chitosan hydrogel composite (CM@CS) as an efficient AOP catalyst for the degradation of atrazine (ATZ) activated by peroxymonosulfate (PMS). The CM@CS composite demonstrated exceptional catalytic performances, particularly at low ATZ concentrations (0.1 mg/L). The degradation rate achieved nearly 100 % with 10 mg CM@CS and 0.01 mM PMS, showing superior catalytic efficacy compared to that of the Co-MoS2 (CM) powder. Besides, the CM@CS composite primarily activated PMS through a non-radical pathway dominated by singlet oxygen (1O2), distinguishing from the radical-driven mechanisms by CM catalysts. This non-radical behavior is attributed to structural and electronic modifications induced by the hydrogel matrix, including enhanced carbonyl functionality and improved charge transfer efficiency. The CM@CS composites exhibited high degradation efficiency across various water matrices due to the reliability of the non-radical pathway, minimal metal ion leaching benefited from the confinement and fixation of active sites in hydrogels, and excellent recyclability. These findings highlight CM@CS as a promising catalyst for advancing non-radical PMS activation mechanisms for applications in practical water remediation.

Abstract ：
Photocatalytic conversion of chemical fuels has emerged as a most challenging subject in photocatalysis which is considered as one of the sustainable solutions for environmental issues related to the energy shortage and anthropogenic carbon emissions. Herein, unique heterostructures of ZnCdS nanoplates with Bi2S3−terminated edges were prepared through a facile cation exchange pathway, by which the controlled photocatalytic CO2 conversion was achieved. The optimized BZCS–NS−5 photocatalyst exhibited an excellent capacity of CO2 photoreduction with a CO production rate of ca. 513.2 ± 5.1 μmol g−1 h−1 and a selectivity of ca. 91.0%, which were among the highest activities for sulfide photocatalysts documented in the literature. The outstanding photocatalytic performance was attributable to the formation of Z−scheme heterostrucutres between Bi2S3 and ZnCdS, in a way the separation and migration of photocarriers were accelerated. This work thus provides a feasible strategy for the construction of heterostructures to enhance the activity and selectivity of CO2−to−CO conversion via delicate design and controlled synthesis of photocatalysts. © 2022 Chongqing University

Abstract ：
Pesticides and its degradation products, being well-known residues in soil, have recently been detected in many water bodies as pollutants of emerging concerns, and thus there is a contemporary demand to develop viable and cost-effective techniques for the removal of related organic pollutants in aqueous phases. Herein, a visible-light -responsive Fenton system was constructed with iron-doped bismuth oxybromides (Fe-BiOBr) as the catalysts. Taking the advantage of sustainable Fe(III)/Fe(II) conversion and optimized H2O2 utilization, the optimal Fe-BiOBr-2 catalyst showed an excellent atrazine removal efficiency of 97.61% in 120 min, which is superior than the traditional homogeneous Fenton and the majority of heterogeneous processes documented in the literature. In this photo-Fenton system, hydroxyl ( center dot OH) and superoxide ( center dot O 2 -) radicals were dominant active species contributed to the oxidative degradation of atrazine. Due to the production of various active radicals, five degradation pathways were proposed based on the identification of intermediates and degradation products. Overall, this work not only demonstrates a fundamental insight into creating highly efficient and atom economic photo-Fenton systems, but also provides a complementary strategy for the treatment of organic pollutants in water.(c) 2023 The Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.

Abstract ：
Potential health risks related to environmental endocrine disruptors (EEDs) have aroused research hotspots at the forefront of water treatment technologies. Herein, nitrogen-doped titanium dioxide/schwertmannite nanocomposites (N-TiO2 /SCH) have been successfully developed as heterogeneous catalysts for the degradation of typical EEDs via photo-Fenton processes. Due to the sustainable Fe(III)/Fe(II) conversion induced by photoelectrons, as- prepared N-TiO2 /SCH nanocomposites exhibit much enhanced efficiency for the degradation of bisphenol A (BPA; ca. 100% within 60 min under visible irradiation) in a wide pH range of 3.0-7.8, which is significantly higher than that of the pristine schwertmannite (ca. 74.5%) or N-TiO2 (ca. 10.8%). In this photo-Fenton system, the efficient degradation of BPA is mainly attributed to the oxidation by hydroxyl radical (center dot OH) and singlet oxygen (1 O2 ). Moreover, the possible catalytic mechanisms and reaction pathway of BPA degradation are systematically investigated based on analytical and photoelectrochemical analyses. This work not only provides a feasible means for the development of novel heterogeneous photo-Fenton catalysts, but also lays a theoretical foundation for the potential application of mineral-based materials in wastewater treatment.

Abstract ：
The substantial presence of antibiotics in aquatic environments remains as a critical environmental issue that needs to be urgently addressed. In this study, mimetics of C-Dots/siderite heteroaggregates (CSI) were studied in a visible-light-responsive Fenton system as a platform for the degradation of antibiotics in contaminated water. By virtue of the excellent electron transfer of C-Dots, the sustained conversion cycles of Fe(II) -* Fe(III) -* Fe(II) in CSI were greatly accelerated, and meanwhile the H2O2 utilization was enhanced. The optimized CSI-3 nanocomposite displayed a prominent degradation efficiency towards a series of tetracycline analogs at ppb levels. Density functional theory (DFT) calculations indicated the excellent photo-Fenton catalytic performance of CSI originated from the increased d-band center and electron density, which considerably improves the utilization of H2O2. Both experimental and theoretical studies revealed that the correlated toxicity of degradation intermediates was significantly decreased. Additionally, a continuous flow device integrating the CSI photoFenton system maintained a high degradation efficiency after long-term treatment of simulated chlortetracycline wastewater. The presented work thereby confirms a spontaneous remediation process for the decontamination and detoxification of persistent organic pollutants under the action of heteroaggregates formed by engineered nanoparticles and natural minerals.
