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 using Te nanowires (NWs) as seeds. Experimental results and series in situ spectroscopic characterization unveiled that the Te NWs serve as branches, enable rapid charge transport and promote effective separation of photogenerated electrons and holes, resulting in efficient visible-light-driven H₂O₂ production with a high yield of 1920 μmol g⁻¹ h⁻¹.
