Single-atom catalysts (SACs) for photocatalytic hydrogen peroxide (H2 O2 ) generation are researched but it is still challenging to obtain high H2 yields. Herein, graphite carbon nitride (FeSA /CN) confined single Fe atoms with N/O coordination prepared, and FeSA /CN shows production via oxalic acid activation. Under visible light illumination, the concentration of generated by can achieve 40.19 mM g-1 h-1 , which 10.44 times higher than that g-C3 N4 . The enhanced be attributed formation metal-organic complexes rapid electron transfer. Moreover, activation photocatalysts revealed 3,3',5,5'-tetramethylbenzidine oxidation. results display capacity facilitates Finally, density functional theory calculation demonstrates chemically adsorbed on atomic sites. adsorption energy from -0.555 -1.497 eV, bond length OO extended 1.235 1.292 Å.

The regulation of heterogeneous material properties to enhance the peroxymonosulfate (PMS) activation degrade emerging organic pollutants remains a challenge. To solve this problem, we synthesize S-scheme heterojunction PBA/MoS2@chitosan hydrogel achieve photoexcitation synergistic PMS activation. constructed photoexcited carriers undergo redox conversion with through transfer pathway driven by directional interface electric field. Multiple pathways greatly reactive oxygen species generation, leading significant increase in doxycycline degradation rate. Meanwhile, 3D polymer chain spatial structure chitosan is conducive rapid capture and electron transport advanced oxidation process, reducing use transition metal activator limiting leaching ions. There reason believe that regulated will provide new perspective for future design research on enhancing heterologous catalysis process.

Abstract Benefitting from ultra‐high porosity, large specific surface area (SSA), and rich active sites, metal–organic frameworks (MOFs) have emerged as a star material in energy environment related applications, especially photocatalysis. In comparison with conventional photocatalysts, MOFs can be customized terms of electronic structure, photo‐responsiveness, morphological dimensions by rational design, which means that eliminate the need for other species to achieve enhanced photocatalytic performance, such metals, compounds, polymers, may introduce extra costs, time‐consuming, multi‐phase, or an unclear mechanism. Most previous review works MOF photocatalysis mixed self‐tuning assisted‐tuning, often gives incomplete understanding. this work, self‐tunning analyzing component (as clusters, ligands, inclusions), defect (defect engineering, linkers, oxygen vacancies (OVs), crystal facets, dimensions, amorphization) is summarized. Then, outstanding examples these strategies applied water redox, CO 2 /N reduction, organic conversion, environmental treatment are discussed. Finally, opportunities challenges faced analyzed different perspectives. This paper comprehensive systematic on enhance activity.
