Plasmonic Near‐Infrared‐Response S‐Scheme ZnO/CuInS 2 Photocatalyst for H 2 O 2 Production Coupled with Glycerin Oxidation

Abstract Solar fuel synthesis is intriguing because solar energy is abundant and this method compensates for its intermittency. However, most photocatalysts can only absorb UV‐to‐visible light, while near‐infrared (NIR) light remains unexploited. Surprisingly, the charge transfer between ZnO and CuInS 2 quantum dots (QDs) can transform a NIR‐inactive ZnO into a NIR‐active composite. This strong response is attributed to the increased concentration of free charge carriers in the p‐type semiconductor at the interface after the charge migration between ZnO and CuInS 2 , enhancing the localized surface plasmon resonance (LSPR) effect and the NIR response of CuInS 2 . As a paradigm, this ZnO/CuInS 2 heterojunction…
