Te/ZnIn2S4 Nanoleaves with Rich Charge Transport and High Electron-hole Separation Efficiency for Augmented Visible-Light-Mediated Hydrogen Peroxide Generation

Abstract

Designing efficient photocatalysts for H₂O₂ synthesis in pure water remains a significant challenge. Herein, Te/ZnIn2S4 nanoleaves were constructed via an epitaxial growth strategy. Series in-situ spectroscopic characterization unveil that Te NWs serve as branches, enables rapid charge transport and promote effective separation of photogenerated electrons and holes, resulting in efficient visible-light-driven H₂O₂ production.
