Organic transformation by light-driven catalysis, especially, photocatalysis and photothermal denoted as photo(thermal) is an efficient, green, economical route to produce value-added compounds. In recent years, owing their diverse structure types, tunable pore sizes, abundant active sites, metal-organic framework (MOF)-based catalysis has attracted broad interest in organic transformations. this review, we provide a comprehensive systematic overview of MOF-based for First, the general mechanisms, unique advantages, strategies improve performance MOFs are discussed. Then, outstanding examples transformations over introduced according reaction type. addition, several representative advanced characterization techniques used revealing charge kinetics intermediates presented. Finally, prospects challenges field proposed. This review aims inspire rational design development materials with improved catalysis.

Abstract Conventional suspension photocatalysts face stability and efficiency challenges in harsh, unconditioned environments characterized by high alkalinity, salinity, organic species seawater wastewater. Moreover, suspension‐based photothermal‐assisted catalysis presents further challenges, particularly concerning formation of heterojunctions between photothermal materials that disrupt charge‐transfer pathways are exacerbated heating‐induced carrier recombination. Here, a photocatalytic system is proposed which three key photoprocesses: photothermal, photogeneration‐charge separation, photoredox spatially decoupled yet coordinated, aimed at addressing prevalent adsorption‐mediated catalyst deactivation harsh environments. Essentially, the polymeric tandem catalytic (PTPC) film consists TiO 2 /Au CuS layers, separated encapsulated serve as spacer inhibitors to conflicting photochemical‐photothermal corrosion‐resistant redox medium. The PTPC exhibits enhanced light absorption, mass transfer, effect, surpassing traditional catalysts enabling interfacial reactions on passive surface. represents new paradigm photocatalysis, unimpeded photoredox‐photothermal for application hostile plastic waste Such can be used develop localized, onsite solutions H production minimize logistical environmental challenges.

Abstract In this work, nitrogen‐defective g‐C 3 N 4 with different nitrogen defect densities is synthesized for ciprofloxacin photocatalytic degradation. Compared pristine , etched NaBH 1 h exhibits an approximately ten‐fold increase in the rate constant of (CIP) The combined experimental analysis and theoretical calculations reveal that defects can be incorporated into all sites C─N═C most susceptible site. By incorporating to induce states between conduction band (CB) valence (VB), electronic structures are tuned. induced downshifted approach valance band, reaching increased density within optimum ranges accommodate excited electrons narrow bandgap, extend light absorption capability, enhance charge carrier separation transfer efficiency. by 2 over‐introduced a declined performance due deteriorated structure, over‐downshifted turn out new recombination center carriers.

The risk of harmful microorganisms to ecosystems and human health has stimulated exploration singlet oxygen (1O2)-based disinfection. It can be potentially generated via an electrocatalytic process, but is limited by the low production yield unclear intermediate-mediated mechanism. Herein, we designed a two-site catalyst (Fe/Mo–N/C) for selective 1O2 generation. Mo sites enhance generation precursors (H2O2), accompanied intermediate •HO2/•O2–. Fe site facilitates activation H2O2 into •OH, which accelerates •HO2/•O2– 1O2. A possible mechanism promoting through ROS-mediated chain reaction reported. as-developed electrochemical disinfection system kill 1 × 107 CFU mL–1 E. coli within 8 min, leading cell membrane damage DNA degradation. effectively applied medical wastewater.
