Abstract
ZnIn2S4 as a photocatalyst for photosplitting water into H2 exhibits some fascinating advantages, such as low toxicity, good crystallinity, and considerable chemical stability. Currently, developing ZnIn2S4-based composite photocatalysts with different morphologies has received wide attention in order to improve the photocatalytic activity. In this contribution, a new ZnIn2S4/RGO/MoS2 photocatalytic system has been designed. The presence of the RGO is confirmed by x-ray photoelectron spectroscopy and FT-IR spectra. By optimization of solvothermal reaction temperatures, reaction time, and RGO introduction amount, up to 1.62 mmol/h ⋅ g of hydrogen evolution rate has been achieved.
