MoS2 is a layered semiconductor material which has a band gap of 1.9 eV. Owing to its visible light activity, MoS2 has been widely investigated for photocatalytic application. It is well established that the photocatalytic activity depends on its structure, morphology, size, etc. In this work, layered MoS2/ZnS were synthesized and the effect of ZnS on the structure and morphology of MoS2/ZnS nanocomposites has been investigated. Structural analysis of the MoS2/ZnS reveals formation of hexagonal and cubic phase of MoS2 and ZnS for all samples. Morphological analyses were performed using FESEM (Field Emission Scanning Electron Microscopy) and HRTEM (High Resolution Transmission Electron Microscopy) revealed the formation of 2D layered MoS2 and MoS2/ZnS nanosheets. XPS analysis confirms the presence of Mo 3d, Zn 2p, and S 2p states in the composition. MoS2/ZnS sample with 0.010 M of ZnS showed the highest efficiency by degrading 99.89% of Methylene Blue (MB) in 32 min. This work can give some perspectives on the construction of noble catalysts for visible-light driven photocatalysis.
