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.

Abstract The artificial photosynthesis of hydrogen peroxide (H 2 O ) using semiconductor photocatalysts is gaining attention as an eco‐friendly and energy‐efficient method. Covalent organic frameworks (COFs) show great promise in enhancing photocatalytic H production due to their tunable structures functional diversity. However, the efficiency generation close photoelectric properties COFs microenvironment active sites. Herein, synthesis pyridyl‐imine‐functionalized (PyIm‐COFs) featuring donor–acceptor (D–A) moieties improve reported. By employing benzothiadiazole (BT) units with varied fluorine substitutions, electronic environment sites, optimizing selective two‐electron (2e − oxygen reduction reaction (ORR), tuned. Among synthesized COFs, PyIm‐BT_F exhibits highest activity, achieving a rate 5342 µmol g −1 h . importance D–A rational design COF‐based photocatalysts, providing novel strategy for sustainable through optimized site environments, underscored.

Abstract Hydrogen peroxide (H 2 O ) is an environmentally friendly reagent, and organic semiconductors (OSCs) are ideal photocatalysts for the synthesis of H due to their well‐defined molecular structure, strong donor‐acceptor interactions, efficient charge separation. This review discusses regulatory mechanisms functional group modifications in tuning photocatalytic performance OSCs, highlighting relationship between structure catalytic performance. For example, electron‐regulating groups, such as cyano halogen, induce dipoles, facilitating migration photogenerated electrons. Fluorine groups optimize band prolong carrier lifetime high electronegativity. π‐Conjugated extension like anthraquinone thiophene, expand conjugation, improve visible light capture, stabilize intermediates through redox cycles. Hydroxyl enhance surface hydrophilicity promote activation, while imine bond protonation adjusts distribution improves selectivity cycle stability. Multi‐active site sulfonic acid amide, accelerate reaction kinetics inhibit decomposition. Functional absorption, separation, reactions electronic regulation, intermediate adsorption optimization, proton‐electron transfer. Future work should integrate machine learning identify optimal combinations develop green functionalization strategies photocatalyst synthesis.
