The current study aims to synthesize and characterize Calcium Molybdate-Graphene Oxide (CaMoO4@GO) nanocomposite under ultrasonic irradiation. Primarily, degradation of Methylene blue (MB) under Uv-Vis light was investigated to measure the photocatalytic properties of the as-synthesized CaMoO4@GO nanocomposite. In addition, various graphene oxide concentrations were applied to investigate its impact on the optical and photodegradation properties of calcium molybdate. X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectra energy dispersive analysis of X-ray (EDS) were used to characterize CaMoO4@GO nanocomposite. DRS results demonstrated that GO influenced significantly the optical properties of CaMoO4 as much as band gap of CaMoO4@GO nanocomposite shows a redshift in comparison with pure CaMoO4. Consequently, photocatalytic results demonstrated that adding GO causes to increase photodegradation of MB form 65% (CaMoO4) to 89% (CaMoO4@GO).
