Abstract
The hierarchical AuNPs/Cd0.5Zn0.5S hybrids are directly fabricated via a facile one-step in-situhydrothermal method. The as-prepared AuNPs/Cd0.5Zn0.5S hybrids demonstrate superior photocatalyticperformance toward hydrogen production under visible light irradiation. The hydrogen evolution rate ofthe 5 wt% AuNPs/Cd0.5Zn0.5S synthesized with in-situ hydrothermal method can be 7.1 times greater thanthat of pure Cd0.5Zn0.5S and as much as 2.5 times of 5 wt% AuNPs loaded Cd0.5Zn0.5S synthesized withphotodeposition method. Systematical investigations reveal that the enhanced photocatalyticperformance of the one-step in-situ prepared AuNPs/Zn0.5Cd0.5S can be attributed to the inherentSPR effect and favorable electron transfer properties of AuNPs, as well as the rational hierarchicalnanoarchitectures that allow AuNPs to be uniformly incorporated into Zn0.5Cd0.5S matrix. This one-stepin-situ fabrication method provides a simple and efficient route to synthesize well-definedheterocatalysts.
