An effective visible light catalyst was successfully fabricated from a nanorod-like MoO

/ZnO (MZ) nanocomposite using a simple hydrothermal method for the decomposition of the dye methylene blue (MB). In addition to XRD, FT-IR, SEM, EDX-Color mapping, DRS-UV, and XPS analysis, a variety of other physicochemical measurements were used to validate the as-prepared MZ nanocomposite. These results confirm the synthesis of nanorod-like MZ composite by successive steps. A MZ nanocomposite was demonstrated to be a superior catalyst for the degradation of MB dye when exposed to visible light. It is evident that the MZ nanocomposite is more effective than the host material for the degradation of MB dye. Moreover, the stability and reusability of the MZ nanocomposite also exhibit better results. The degradation efficiency of the MZ nanocomposite is 97.68% towards the degradation of the MB dye.
