Abstract
Hydrothermal synthesis of CuMoO4 photocatalyst for the photocatalytic degradation of methylene blue (MB) in the aqueous phase was performed under visible light illumination. The produced nanoparticle was characterized using X-ray Powder Diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Ultraviolet–visible diffuse reflectance spectra (DRS-UV), Energy-dispersive X-ray (EDAX) spectroscopy and X-ray photoelectron spectroscopy (XPS) to investigate the nanoparticles' structures, functional groups, morphologies, bandgap energy, qualitative and oxidation state of elemental analysis. The methylene blue (MB) photodegradation process using 30 mg of the photocatalyst at 1 μM concentration resulted in a greater degradation efficiency under visible light. A maximal photocatalytic performance of 94.70% was attained for 50 min. The effects of variables on the photocatalytic process, such as adsorbent dosage, catalyst and scavenger concentrations, recycling effectiveness, and MB concentration, have been thoroughly studied.
