利用太阳能分解水的半导体催化剂是最有希望解决能源危机和全球环境问题的方法之一。利用连续外延生长和阳离子交换法成功构建了独特的三元CuInS₂-Cd(In)S-MoSe₂纳米异质结构,并应用在光催化析氢反应(HER)中。实验结果表明,合成的CuInS₂-Cd(In)S-MoS₂异质结在HER中表现出良好的光催化活性和稳定性。该光催化剂设计方法可以应用到其他半导体材料系统,为设计具有整体高分解水性能的光催化剂提供有效的策略。

Semiconductor catalysts for solar energy-driven water splitting are considered as one of the most promising solutions to global energy crisis and environmental problems.Herein,unique ternary CuInS₂-Cd(In)S-MoSe₂ nano heterostructures are successfully constructed by using continuous epitaxial growth and cation exchange method,and applied in photocatalytic hydrogen evolution reaction (HER).Experimental results show that the synthesized CuInS₂-Cd(In)S-MoS₂ nano heterostructures exhibit excellent photocatalytic activity and stability for HER.Such photocatalyst design approach can be applied to other semiconductor material systems,which provides an effective strategy to design photocatalysts with performance for overall high water splitting.
