Visible‐Light‐Induced Photochemical Hydrogen Evolution and Degradation of Crystal Violet Dye by Interwoven Layered MoS ₂ /Wurtzite ZnS Heterostructure Photocatalyst

Abstract

Abstract The photocatalytic properties of a material predominantly depend upon the material fabrication. In the last few years, sulfide based nanomaterials were used for their extraordinary efficiency due to their structural and morphological features. Present work is focused on the preparation of bimetallic layered molybdenum‐wurtzite zinc sulfide heterostructure by facile hydrothermal method. The prepared MoS 2 −ZnS was characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer‐Emmett‐Teller (BET) surface analysis and X‐ray photoelectron spectroscopy (XPS). MoS 2 −ZnS showed high photocatalytic hydrogen evolution reaction (HER) and dye degradation compared to pure ZnS and MoS 2 . The synergistic effect of layered MoS 2 and wurtzite ZnS would have amplified the photocatalytic HER activity and degradation of crystal violet dye under visible light irradiation; the electron‐hole recombination was significantly reduced due to the heterostructured arrangement of MoS 2 ‐ wurtzite ZnS
