2D/3D BiVO₄@ZnIn₂S₄ Hierarchical Heterojunction for Enhanced One-Electron Oxygen Reduction Kinetics of H₂O₂ Artificial Photosynthesis

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 5, 2025

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.
