摘要：
A novel double Z-scheme WO3/Cd0.97Zn0.03S/CoSx (WO3/CZS/CoSx) photocatalyst was designed to explore the photocatalytic hydrogen production performance. Cd0.97Zn0.03S (CZS) nanoparticles are well loaded onto the surface of WO3 nanorods and further form heterojunction with CoSx nanosheet. The WO3/CZS/CoSx photo -catalyst showed excellent photocatalytic performance with the photocatalytic hydrogen yield of 117.48 mu mol/h, which was 7.58 times higher than that of CZS (15.50 mu mol/h). The established double Z-scheme system inhibited the recombination of photogenerated electrons and holes and promoted the transfer of photogenerated carriers, thus accelerating the photocatalytic hydrogen production process.
