Abstract :

Photocatalytic CO2 reduction into high-value C2+ products such as C2H6 is of great importance but challenging due to their multi-electron steps and high energy barrier of C & horbar;C coupling. Moreover, improving its solar-to-chemical (STC) energy conversion efficiency in pure water beyond the current 1% empirical value is also a significant challenge. Herein, graphite carbon nitride (g-C3N4) nanosheets with controllable carbon (C) doping and nitrogen (N) vacancies (PCCN-x) are designed through a biochar-tailored protocol for efficiently and selectively photo-converting CO2 into C2H6. The optimal PCCN-10 photocatalyst enables the achievement of an exceptional C2H6 activity of 99.14 mu mol g(-1) h(-1) with C2H6 selectivity of 80.33% over 20 h in pure water. A record STC efficiency of approximate to 1.13% for solar fuel production from CO2 and H2O vapor is also achieved without any other energy inputs. Outdoor tests also demonstrated an impressive CO2-to-C2H6 photo-conversion rate of 43.17 mu mol g(-1) h(-1) in pure water, with stable activity over 50 h period. Critically, experimental and theoretical calculations further confirm the pivotal role of bridged C sites and N vacancies in activating CO2 molecules and promoting the formation of C & horbar;C coupling intermediate (*OCCO), which is very beneficial for the production of C2H6. The impressive performance of this work in the photocatalytic conversion of CO2 to high-value C2H6 fuels paves the way for large-scale fuel production and broader sustainable applications.

Abstract :

One of the primary challenges for immune checkpoint blockade (ICB)-based therapy is the limited infiltration of T lymphocytes (T cells) into tumors, often referred to as immunologically "cold" tumors. A promising strategy to enhance the anti-tumor efficacy of ICB is to increase antigen exposure, thereby enhancing T cell activation and converting "cold" tumors into "hot" ones. Herein, we present an innovative all-in-one therapeutic nanoplatform to realize local mild photothermal- and photodynamic-triggered antigen exposure, thereby improving the anti-tumor efficacy of ICB. This nanoplatform involves conjugating programmed death-ligand 1 antibody (aPD-L1) with gadolinium-doped near-infrared (NIR)-emitting carbon dots (aPD-L1@GdCDs), which displays negligible cytotoxicity in the absence of light. But under controlled NIR laser irradiation, the GdCDs produce combined photothermal and photodynamic effects. This not only results in tumor ablation but also induces immunogenic cell death (ICD), facilitating enhanced infiltration of CD8(+) T cells in the tumor area. Importantly, the combination of aPD-L1 with photothermal and photodynamic therapies via aPD-L1@GdCDs significantly boosts CD8(+) T cell infiltration, reduces tumor size, and improves anti-metastasis effects compared to either GdCDs-based phototherapy or aPD-L1 alone. In addition, the whole treatment process can be monitored by multi-modal fluorescence/photoacoustic/magnetic resonance imaging (FLI/PAI/MRI). Our study highlights a promising nanoplatform for cancer diagnosis and therapy, as well as paves the way to promote the efficacy of ICB therapy through mild photothermal- and photodynamic-triggered immunotherapy.

Step-scheme/Mott-Schottky integrated heteroiunctions in BiFeO3/ZnIn2S4/ Ag hollow nanospheres: Facilitating efficient piezo-photocatalytic activation of peroxydisulfate to enhance nizatidine degradation and antibacterial activity SCIE

Abstract :

The piezo-photocatalysis enhanced by piezoelectric nanogenerators is considered one of the most effective methods for treating emerging contaminants (ECs) in environmental water. In this study, BiFeO3/ZnIn2S4/Ag (BFO/ZIS/Ag) with boosting piezo-photocatalytic performance was synthesized by modulating the interaction between the step-scheme (S-scheme) heterojunction and the Mott-Schottky barrier. The catalytic rate of the optimized BFO/ZIS/Ag-0.01 catalyst is 4.85 x 10-2 min- 1 for the degradation of niazitidine (NZT) under both ultrasonic and visible light radiation, which is respectively 4.3 and 4.8 times higher than that of pure BFO and ZIS. Furthermore, the total organic carbon (TOC) test revealed that NZT degradation reached 98.4 % after 120 min of continuous reaction. This enhanced piezo-photocatalytic performance is mainly due to the synergistic effect of integrated heterojunction and piezoelectric field. DFT calculations revealed that the charge transfer enhancement at the heterogeneous interface resulted from directional electron transfer to ZIS via Zn-O and S-Ag channels, following the introduction of Ag nanoparticles, which shortened the carrier separation path. Additionally, BFO bent the band of the composite catalyst, promoting carrier separation. These resulted in the generation of abundant highly active 1O2, which specifically targeted and disrupted stable NZT molecules. Moreover, BFO/ZIS/Ag-0.01 exhibited strong inhibitory and antibacterial effects against Escherichia coli and Staphylococcus aureus via electrostatic adsorption and ionization. This study offers new insights into the restoration of aquatic environments and bacterial disinfection through the use of piezoelectric catalytic materials.

Multi-Energy Integrated Photocatalysis for Antitumor Therapy ESCI
期刊论文 | 2025 | EXPLORATION
Abstract&Keyword Cite

Abstract :

Photocatalysis has been recognized as a promising approach in cancer theranostics over the past years. To enhance therapeutic outcomes and overcome current limitations, significant attention has been directed toward the development of multi-energy integrated photocatalytic systems, particularly piezo-photocatalysts and photothermal-photocatalysts. Piezo-photocatalysis combines the piezoelectric effect with photocatalysis, offering superior efficiency, targeted action, and improved safety compared to traditional photocatalytic methods. By harnessing both mechanical and optical stimuli, this approach enables more precise and effective cancer therapies. On the other hand, photothermal-photocatalysis integrates heat induced by light with photocatalytic reactions, accelerating reaction rates and promoting the generation of reactive oxygen species. The synergistic interaction of heat and photocatalysis enhances tumor cell apoptosis more effectively than either modality alone. This review provides a systemic overview of the emerging multi-energy integrated photocatalytic strategies for cancer treatment. It begins with an exploration of the principles of piezo-photocatalysis and its potential to improve cancer therapies such as piezoelectric-enhanced single-modal photodynamic therapy (PDT), dual-modal sono-photodynamic therapy, and triple-modal hydrodynamic therapy/gas therapy (GT)/chemotherapy. Next, we delve into photothermal-photocatalysis and examine how its integration with additional treatment modalities, such as dual-modal photothermal/photocatalytic therapy (PTT/PCT) and PTT/PDT, can enhance therapeutic efficacy. Furthermore, we discuss more complex multi-modal treatments, including triple-modal PTT/PCT/chemotherapy, PTT/PCT/chemodynamic therapy (CDT), PTT/PCT/GT, PTT/PCT/immunotherapy (IT) and tetra-modal PTT/PCT/CDT/chemotherapy, PTT/PCT/CDT/ferroptosis therapy (FT), PTT/PCT/FT/IT, and PTT/PCT/GT/IT. Finally, we address the challenges and future directions in advancing these novel therapeutic paradigms. This review aims to provide a comprehensive resource for future research dedicated to advancing innovative multi-energy integrated photocatalytic systems in the field of cancer nanotheranostics.

Key highlights include in-depth analyses of the dynamic nature of catalytically active iron phases, novel materials, and state-of-the-art catalyst design strategies to overcome the challenges of Anderson-Schulz- Flory (ASF) limitations and low olefin selectivity. With a comprehensive discussion on reaction mechanisms, catalyst composition, and performance-driving factors, this review sets the stage for pioneering advancements in catalyst development. Thus, by bridging fundamental insights with cutting-edge technologies, this work provides strategic guidance for developing the next generation of efficient and sustainable catalytic systems for CO2 hydrogenation.

Biochar-Tailored Carbon Nitride Enables Piezo-Photocatalytic H2O2 Production via Boosted Charge Transport SCIE

Abstract&Keyword Cite

Abstract :

Piezo-photocatalytic systems enable efficient H(2)O(2)generation, presenting a promising mechanical-energy-to-chemical-energy conversion pathway. However, limitations, including insufficient polarization efficiency and poor directional charge transfer, persist in current piezoelectric semiconductors, constraining the photocatalytic performance. Here, we develop a biochar-tailored method to fabricate PCCN-x, a modified carbon nitride nanosheet incorporating nitrogen defects and carbon bridges, which demonstrates high efficiency in piezo-photocatalytic H2O2 generation. Experimental and theoretical analyses reveal that introducing nitrogen defects together with carbon incorporation creates an asymmetric configuration in the triazine unit, generating a pronounced dipole field that drives spontaneous polarization. This configuration enhances oriented charge migration at the nitrogen active sites, enabling efficient O-2(-) adsorption and activation via an indirect two-electron reduction pathway. The optimized PCCN-10 yields 4.61 mmol g(-1) h(-1) H2O2 in the absence of cocatalysts, outperforming most previously reported piezo-catalysts and g-C3N4-based photocatalysts. Remarkably, the system sustains high piezo-photocatalytic performance (2.19 mmol g(-1) h(-1)) even when operating in a pure water system. Overall, this work develops a multifield-coupled catalytic framework based on biochar-tailored defect engineering, offering a new design principle for sustainable H2O2 production and advancing multifunctional material systems for green energy applications.

Abstract :

We present a spider web-inspired gelatin (GE) bioplastic engineered by the integration of natural tea polyphenols (TP), gelatin, and bio-based hyperbranched polyester (HBPE) synthesized from glycerol and itaconic anhydride. The resulting TP-HBPE-GE exhibits multifunctionality, including balanced optical properties for food packaging (52% visible light transmission and 99.8% UV blocking), a mechanically tunable biomimetic network enabling glycerol-free customization of strength and toughness (11.0-33.8 MPa tensile strength and 21.6%-125.3% elongation at break), dual moisture resistance combining hydrophobic surfaces (113.3 degrees contact angle) and low vapor permeability with high barrier properties (803.1 g (m2 day)-1), and bioactive preservation through antioxidant (88.6% DPPH scavenging) and antimicrobial actions (complete eradication of E. coli and S. aureus). Practical validation demonstrates superior cherry tomato preservation compared to commercial polyvinyl chloride (PVC), maintaining firmness and retaining nutrients over 15 days. The system embodies circular design principles through its renewable composition (gelatin, TP and HBPE), energy-efficient processing (water-based fabrication and thermal remodeling), closed-loop recyclability (conversion to adhesives/coatings), and full biodegradation within 28 days. This architecturally engineered bioplastic establishes a sustainable packaging paradigm aligned with green chemistry principles, including prioritization of renewable feedstocks, minimized process environmental footprints, valorization of waste films as adhesives and coatings, and ensured end-of-life biodegradability.

Pt-Activated Surface Nucleophilicity on High-Entropy Oxides Enables Superior Biomass Upgrading SCIE

Abstract&Keyword Cite

Abstract :

Strategic engineering of the surface electronic structure in high-entropy oxides (HEOs) to enable efficient and selective electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) presents significant challenges. Herein, a Pt-decorated Zn(AlCrMnFeCo)2O4 (Pt/HEO) catalyst is fabricated and harnessed the strong metal-support interaction (SMSI) between Pt and HEO, alongside the intrinsic strong intermetallic synergies within the HEO lattice, to strategically engineer the surface electron configuration of HEO. Pt/HEO catalyst achieves a 2,5-furandicarboxylic acid (FDCA) production rate of 80 mA cm-2 at 1.38 V versus RHE with a near-unity Faradaic efficiency (approximate to 99.8%) and selectivity (approximate to 96.8%). These performances surpass majority of recently reported state-of-the-art catalysts. The excellent performance originates from the anchored Pt-induced charge redistribution within the HEO lattice, driven by the strong intermetallic synergies among multiple metal components. The resulting electronic effect strengthens nucleophilic interaction between HMF and metal-oxyhydroperoxide (M & horbar;OOH) on metal-oxygen (M & horbar;O) sites. This work establishes a viable strategy for strategic electronic modulation of HEOs, offering a paradigm for designing robust electrocatalysts to advance sustainable biomass valorization.

Abstract&Keyword Cite

Abstract :

Metal-organic frameworks (MOFs) integrating fluorescence sensing and photocatalytic functions remain challenging to construct due to competing structural requirements. Herein, we report the synthesis, spectral and crystallographic characterization of two novel group organic skeletons composed of 5-(1H tetrazol-5-yl) isophthalic acid (H3L) ligand (formula [Zn2L(H2O)(3)](n)& sdot;nNO(3)(Zn2L-MOF-1) and [Pb2L(OH)(H2O)](n)& sdot;nH(2)O (Pb2L-MOF-2). Single crystal X-ray analysis shows that Zn2L-MOF-1 forms an infinite three-dimensional network structure and a double interpenetrating pcu topology through two symmetrical metal centers and a tetrazolium of L3- ligand. Pb2L-MOF-2 further forms a three-dimensional supramolecular structure through hydrogen bonding between L3- ligand and free water molecules. Zn2L-MOF-1 can be used as an efficient multifunctional fluorescent material for the high sensitivity detection of metal cations Pb2+, Hg2+ and nitrobenzene (NB). The minimum limit of detection (LOD) can reach 10(-7) M-1. In addition, Pb2L-MOF-2 was used as a light-driven catalyst for the photodegradation of tetracycline (TC) antibiotics, with a photodegradation rate of 90.16% within 140 min. The possible sensing and photocatalytic mechanism of MOFs is explained through the comprehensive analysis of experiment and molecular orbital theory. This work establishes photoactive 3D MOFs as dual-purpose materials for environmental monitoring and remediation, with topology-dependent property modulation offering new design paradigms.
