摘　　要：硫化锌镉(Cd1-xZnxS,0<x<1)固溶体因其优异的活性、可调谐的能带结构在光催化分解水制氢领域备受关注,但其较快的光生电荷复合速率和光腐蚀仍阻碍了其进一步应用。因此,研究者们针对其固有缺陷进行了大量改性工作。我们首先简述了光催化反应热力学与动力学特征,随后详细综述了近年来Cd1-xZnxS在光解水制氢领域的研究进展,包括其结构调控、异质结构建、杂原子掺杂等方面,简要分析了Cd1-xZnxS光催化分解水所面临的挑战和问题,并对近期研究进行了展望。Cd1-xZnxS(0<x<1)solid solution has received much attention in the field of photocatalytic water splitting for its tunable band position and excellent activity.However,the dramatic charge recombination and photocorrosion of Cd1-xZnxS have long been the two main barriers that limiting its further application.Therefore,many strategies,including morphology modulation,constructing heterojunction and elemental doping et al.have been employed to overcome the above two inherent defects of Cd1-xZnxS.This mini-review first briefly described the thermodynamic and kinetic characteristics of photocatalytic reaction,and the recent progress of Cd1-xZnxS solid solution on photocatalytic H2 evolution were reviewed.The challenges that lying in its further application were also summarized in the last.
