摘要

How to inhibit the photogenerated carrier recombination for enhancing the photocatalytic properties of semiconductor is still a key scientific problem to be solved. In this study, a novel Z-scheme CdS/CoMoO4 (CdS/CMO) heterojunction photocatalyts were constructed by a two-step hydrothermal method. The photocatalytic degradation properties of CdS/CMO heterojunction photocatalysts for RhB was significantly enhanced compared to CdS and CoMoO4. The remarkable photocatalytic degradation efficiency could be credited to the expanding visible light absorption and construction of Z-scheme heterojunction. This work demonstrates a novel Z-scheme heterojunction photocatalyst for the highly effective removal of organic dyes, providing fresh ideas for water purification.
