Novel approach for the synthesis of Fe₂O₃-CuO-MoO₃ nanocomposite was established using sol-gel and ultra-sonication setup. The conformation of the synthesized nanocomposite was done using Fourier transform-infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy-energy dispersive X-ray (SEM-EDX) techniques. The chemistry of product thermal stability and decomposition was studied using thermo gravimetric analysis-differential scanning calorimetery (TGA-DSC) with respect to increase in temperature. The optical properties were studied using UV-visible spectroscopy via Wood and Tauc relation. XRD data indicates the presence of orthorhombic crystal system with crystallite size of 4.45 and 38.71 nm using Scherrer equation and Williamson-Hall equations, respectively. The particle size was calculated using transmission electron microscopy (TEM) and found to be 12.67 nm. The catalytic ability of synthesized nanocomposite was studied against methylene blue, and the decrease in percentage degradation from 5 to 30% was observed in nanocomposite prepared from sol-gel to ultra-sonication method.
