ZnS–MoS 2 nano-heterostructure: efficient photocatalyst for dye removal under sunlight

We report hydrothermal synthesis of ZnS–MoS 2 nano-heterostructure and characterization by XRD, UV–Vis, FTIR and FESEM followed by their systematic photocatalytic activity under sunlight irradiation. The synthesized ZnS–MoS 2 nano-heterostructure exhibited a unique property, enabling efficient charge separation and extension in visible spectrum. This enhanced light absorption enabled the electron-hole pairs generation, which subsequently participated in the degradation of MB dye molecules. The ZnS–MoS 2 synthesized at 48 h shows excellent performance of 97% degradation in 30 min owing to the fact that the sample has enhanced crystallinity, good charge carrier ability optimal heterojunction formation and Well-defined morphology with a reduced number of defects. The combination of ZnS and MoS 2 in a well-designed nano-heterostructure represents a significant advancement in the field of photocatalysis, offering a promising solution for addressing environmental challenges in an efficient and sustainable manner.
