Hydrogen peroxide (H2O2) finds extensive applications in various industries, particularly the environmental field. The photocatalytic production of H2O2 through oxygen reduction reaction (ORR) or water oxidation (WOR) offers a promising approach. However, several challenges hinder effective on-site production, such as rapid electron–hole pair recombination, inefficient visible light utilization, and limited selectivity formation. Thus, developing efficient photocatalysts to overcome these is crucial. This review comprehensively outlines development their modification techniques. It also summarizes compares yield apparent quantum among with without use organic sacrificial reagents. Density functional theory (DFT) calculations propose band structure mechanisms underlying H2O2. Finally, this explores potential photocatalytically produced guides design optimization photocatalysts, facilitating continued advancement application contexts.

Hydrogen peroxide (H2O2) artificial photosynthesis converts low-density solar energy into storable clean chemical energy, which is an important hot topic in green chemistry. Constructing heterojunctions effective tactic to enhance the oxygen reduction kinetics of H2O2 photosynthesis, however, actual source activity remains ambiguous. Here, a series BiVO4@ZnIn2S4 hierarchical (BZ-x, x = 0.4, 0.8, 1.2) were elegantly designed through piecing two-dimensional (2D) BiVO4 nanosheets onto surface three-dimensional (3D) ZnIn2S4 flower-like microspheres by straightforward ethanol ultrasound-induced self-assembly strategy. These BZ-x photocatalysts exhibit significantly enhanced photocatalytic production rates across wide pH range (3–13) compared with those pristine and ZnIn2S4, optimal BZ-0.8 showing excellent rate as high 1585.99 μmol g–1 h–1. Comprehensive analysis reveals that 2D 3D form Z-scheme heterojunction, can deliver favorable coupling between photogenerated electrons adsorption O2 at interface heterojunctions, thereby accelerating two-step one-electron kinetic process. This study provides new perspective for improving introducing heterojunction strategies.

Hydrogen peroxide (H2O2) generation via a photocatalytic O2 reduction reaction has been considered an economically efficient and environmentally friendly synthesis method. However, the productivity of H2O2 production is restricted because sluggish kinetics fast recombination photoinduced excitons. Therefore, superior two-dimensional (2D)–2D WS2/sulfur-doped g-C3N4 (WSCN) hybrid material was successfully fabricated to address associated limitations through combination wet impregnation calcination techniques for production. The effective anchoring WS2 nanoplates onto sulfur-doped (SCN) nanosheets facilitates separation excitons with sturdy redox properties, which attributable establishment S-scheme heterojunctions between SCN W–S bonding as substantiated by X-ray photoelectron spectroscopy (XPS) analysis. bond at interface acts bridge charge segregation pathways. Among all, 2.5 WSCN displays exceptional 817 μmol, 7.9- 2.68-fold higher than those pristine SCN, respectively. solar-to-chemical conversion efficiency found be 0.24%, whereas apparent quantum yield estimated 3.19% 420 nm irradiation. improved activity figured out cathodic photocurrent −1.51 mA cm–2 delayed excitons, supported photoluminescence electrochemical impedance measurements. charge-transfer pathway well validated radical scavenging experiment work function, evaluated from VB-XPS analysis in situ XPS measurement. This research offers paradigmatic idea constructing photocatalyst generation.
