Coupling ZnInS Nanosheets with MoS Hollow Nanospheres as Visible-Light-Active Bifunctional Photocatalysts for Enhancing H Evolution and RhB Degradation.

In this study, Mo-glycerate was used as a precursor to create MoS hollow nanospheres (HNS), which were then used for the first time to modify ZnInS nanosheets to create MoS HNS/ZnInS photocatalysts. The findings demonstrate that MoS HNS/ZnInS heterojunctions exhibited remarkably boosted photocatalytic properties and excellent reusability for both RhB degradation and H evolution without the use of Pt as a co-catalyst. Among the heterojunctions, the RhB degradation and H evolution efficiencies of the optimized MoS HNS/ZnInS-3 wt % composite were almost 5 and 34 times higher than those of ZnInS, respectively. The excellent performance of MoS HNS/ZnInS-3 wt % might be attributed to the expansion of the visible-light response range and the accelerated separation efficiency of photo-induced carriers, according to the findings of the optical property tests. Based on the established band gap position and characterization results, a potential mechanism for appealing photocatalytic activity over MoS HNS/ZnInS heterojunctions was also postulated.
