Ni(OH)₂ surface-modified hierarchical ZnIn₂S₄ nanosheets: dual photocatalytic application and mechanistic insights

Abstract

The double-charge-receptor role of Ni(OH)2 deposited over ZnIn2S4 towards efficient bi-functional furfuryl alcohol oxidation coupled with H2 production in pure water under anaerobic conditions is revealed.

In situ construction of Ohmic/Schottky-type MoS2/Sv-ZnIn2S4/Cu(OH)2 dual-junction photocatalysts with enhanced water splitting into hydrogen generation activity

“…Subsequently, transition metal phosphides, transition metal hydroxides and transition metal sulfides were developed and applied as alternative cocatalytic materials. 26,27 For example, Lin and coworkers deposited Ni(OH) 2 on the surface of ZIS, and found that Ni(OH) 2 effectively extracted the photoexcited holes from ZIS, inhibited the charge recombination and promoted the hydrogen evolution reaction. 28 Wang et al synthesized ZIS/MoS 2 /CdS nanospheres using a solvothermal method and found that MoS 2 cocatalysts with fast ionic conductivity could quickly expedite the separation and transfer of photoinduced carriers, finally resulting in enhanced photocatalytic activity.…”
