英文摘要Photocatalytic hydrogen production from water exhibits great potential for solar energy conversion. In this work, using monoclinic CaIn2S4 with surface nanostep structure as a model photocatalyst, we demonstrate a facile and efficient strategy for the construction of AO(x)/AuCu/CaIn2S4 (A = Mn, Ni and Pb) composites by site-selective photo-deposition of reductive cocatalyst AuCu alloy and oxidative cocatalyst AO(x) on the edge and groove sites of CaIn2S4 nanosteps, respectively. Compared to single-cocatalyst composites (AuCu/CaIn2S4 and AO(x)/CaIn2S4) and CaIn2S4, the simultaneous deposition of AuCu and AO(x) spatially separate the photogenerated charges and the photocatalytic reaction sites, therefore effectively improving the separation efficiency of charge carriers. Meanwhile, the synergistic effect of AuCu and AO(x) dual cocatalysts notably reduces the apparent activation energy for photocatalytic hydrogen production reaction. This novel dual-cocatalyst composites show enhanced performance for hydrogen production under visible light irradiation. A high rate of hydrogen production of 95.75 mmol h(-1) g(-1) is achieved over MnOx/AuCu/CaIn2S4 composite with the deposition of 0.5 wt% AuCu and 0.2 wt% MnOx. Our work sheds new lights on designing efficient photocatalytic materials with site-selective surface deposition of reductive and oxidative dual cocatalysts for solar energy conversion.
