Abstract Poor light absorption, recombination of photogenerated charges, low surface area, and insufficient catalytically active sites are the most studied conventional bottlenecks photocatalysis processes, which hinder efficiency photocatalytic materials. However, there other less factors such as solubility diffusion reactants in reaction system, also responsible for sluggish kinetics can alter selectivity. The diphase reactions at liquid–solid interface suffer from poor slow transport a medium. emerging triphase photocatalysis, occurs gas–liquid‐solid liquid–liquid–solid has shown potential addressing these less‐studied issues achieved better performance than reactions. This review article mainly focuses on understanding mechanism basic difference between along with requirements photocatalysis. Several examples including CO 2 reduction, N fixation, H O production, organic pollutant degradation discussed detail this review. Finally, summary future directions field provided to guide researchers design remarkable systems excellent efficiencies.

Designing and accumulating quantum dots (QD) onto layered double hydroxide (LDH) for the photocatalytic production of H2 H2O2 is a formidable task. Here, we intended synthesis procedure CdMoSe-QD (CMS)-incorporated NiV-LDH (NV) through facile in situ reflux method explored activities CMS/NV (CNV) heterostructure. CNV-1 exhibits large interface contact area assures excellent interfacial charge transfer ability. Moreover, outstanding rates, i.e., 6.4 2.5 times higher than that pristine NV, respectively, due to formation an S-scheme heterojunction between NV CMS. Both CMS function as n-type semiconductors extend photoresponse visible regions. The composite achieves 1.67% SCC generation 7.36% ACE evolution. activity ascribed anodic photocurrent, confinement effect CMS, surface-active sites, delayed recombination excitons supported by PL EIS measurements. Further, mechanism was authenticated radical scavenging test work function, evaluated UPS measurement. Altogether, this study exemplifies concepts designing CNV heterostructure, which operates via n–n-based aims enhance production.

This study explores the surface modification of TiO2 P25 with nanosized copper (Cu) or nickel (Ni) for photocatalytic hydrogen production via water splitting. Photocatalysts 1 5 wt % metal loadings were synthesized using a cost-effective impregnation method and tested as-prepared (XM/P25) after thermal reduction under flow (XM/P25-r). Pre-calcination was omitted to simplify synthesis. The characterization photocataysts revealed key physicochemical, optical, electronic properties, including distribution oxidation states species their interaction TiO2. TEM EDS showed well-distributed forming nanometric domains on surface. XPS Auger spectroscopy allowed identification different species. After reduction, Cu0 Ni0 phases coexisted oxidized species, enhancing light absorption reducing electron-hole recombination, confirmed by UV-vis DRS PL, respectively. Cu seemed exhibit stronger than Ni ones. Photochemical results that only thermally reduced photocatalysts led immediate production, highlighting need zero-valent an efficient generation. 5Ni/P25-r 5Cu/P25-r outperformed P25, achieving 331 284 μmol H2·gcat -1·h-1, respectively, compared 261 -1·h-1 P25. Although in terms slightly 5Cu/P25-r, latter demonstrated greater stability, possibly due during tests. As-prepared can be activated extended UV irradiation; instance, 5Cu/P25 starts producing 10 h irradiation as result situ color change photocatalyst.

Abstract With the rapid development of clean energy, photocatalytic hydrogen peroxide (H₂O₂) production has emerged as a transformative strategy to decarbonize chemical industry, offering sustainable alternative fossil fuel‐dependent anthraquinone process. Nevertheless, in pathway H₂O₂ production, there are still series negative issues, such insufficient supply protons, difficulty separating electron–hole pair, and low utilization spatial reactive active sites. Therefore, is an urgent need for systematic review latest advancements further enhance production. In this review, three systems comprehensively discussed, oxygen reduction reaction (ORR) system with without sacrificial agents, water oxidation (WOR) accompanied by evolution reaction, dual coupling ORR WOR. By bridging molecular‐scale mechanistic insights system‐level innovation, not only explains fundamental mechanisms but also bridges lab‐scale breakthroughs industrial viability, positioning cornerstone green chemistry renewable energy storage, implications environmental remediation carbon‐neutral synthesis.
