Abstract

Outside Back Cover: AgIn₅S₈ is a promising semiconductor photocatalyst for efficient visible-light photocatalytic hydrogen evolution (PHE). In this review by X. Zheng et al. doi:10.1002/idm2.12120, the recent progress of AgIn₅S₈-based photocatalysts for PHE application are comprehensively discussed, the representative optimization strategies for PHE performance enhancement are summarized, including morphology control, cocatalyst loading, and heterojunction construction, and the current challenges and future perspectives are highlighted. The fundamental studies on AgIn₅S₈ photocatalyst are expected to stimulate research interest in solar-to-hydrogen and promote the development of advanced semiconductor photocatalyst.
