A new NiO-CuO nanocomposite has been successfully synthesized by a sol-gel method using nickel chloride hexahydrate, copper chloride hexahydrate, ammonia and ethylene glycol as a precursors. The resulting material was characterized by XRD, SEM, TEM, EDAX, UV–Visible, FTIR, and TGA-DTA techniques. XRD analysis revealed all the relevant Bragg’s reflections for face-centered cubic and monoclinic structure of NiO-CuO. The average particle size was obtained 25 nm by using the Scherrer equations. The value of particle size determined from XRD was in good agreement with the SEM and TEM analysis. The direct optical band gap was found to be at 3.3 eV. Furthermore, the thermal behaviour of mixed salts has been studied using thermal analysis (TG and DTA). To verify the purity of the composites and the elemental composition of the constituent oxides checked by FTIR and EDAX were performed.
