Here with we reported a detailed synthesis of Fe/Cr co-doped Copper oxide nano particles with a simple and inexpensive wet chemical method. The pure and Fe, Cr substituted CuO nanoparticles was prepared with sol-gel chemical method are expedient for industrial application. The preliminary X – ray diffraction and Rietveld refinement study revealed a pure crystallinity nature with monoclinic crystal with C2/c phase. The average crystallite size was calculated by Scherrer’s formula in order of 21 nm and further observation indicates with increase concentration crystalline size increases. The scanning electron microscopy (SEM) images indicate particles are in 20-30 nm range. The Raman spectroscopic study indicates the existence of molecular groups in the CuO nanoparticles with the doping of Cr and Fe.
