Ultrasonic oscillation synthesized ZnS nanoparticles/layered MXene sheet with outstanding photocatalytic activity under visible light

To raise photocatalytic efficiency of ZnS nanoparticles (ZnS NPs) under visble light, the novel Ti3C2Tix (MXene) material was used to modify ZnS NPs through ultrasonic oscillation. Research results showed that ZnS nano particles (ZnS NPs) were successfully attached on layered MXene sheet, and the resultant 0.1ZnS NPs/MXene (0.1ZnS/M) sample exhibited very high photocatalytic performance under visible light. The degraded velocity of 0.1ZnS/M sample is about 0.02464 min(-1), in which is as 3.2 times as that of pure ZnS (0.0077 min(-1)). Moreover, 0.1 ZnS/M sample displayed good hydrogen production yield about 212 mu mol h(-1). The enhanced catalytic performance was attributed to the excellent property of MXene sheets and the effective interaction between ZnS NPs and MXene sheets.

Automated summary

The ZnS nanoparticles modified with MXene material showed significantly improved photocatalytic performance under visible light, with high hydrogen production yield. The enhanced catalytic performance was attributed to the excellent properties of MXene sheets and the effective interaction between ZnS nanoparticles and MXene sheets.
