A Strains Activity of CuO Nanoparticles using Copper Chloride Dihydrate by Sol-Gel Method

Abstract

Copper(II) oxide (CuO) nanoparticles synthesized by different molarities like 0.1, 0.2 and 0.3 M at calcinations temperature 450 ºC. The XRD results analyzed the prominent peaks corresponding to the monocrystalline nature of CuO nanoparticles and the average crystalline size of CuO nanoparticles size is decreased with increase of molarities. From SEM image of CuO nanoparticles, the particles are well scattered, which are well connected and consistent with the crystal system. The absorption spectra shows the blue shift which can be attributed to the small size of CuO nanostructures. The FTIR spectra confirmed high intense broad band peaks at 496.96 cm-1 and assigned to characteristics band of monoclinic phase CuO nanoparticles were synthesized and calcined at 450 ºC, and the particle size of the nanoparticles was found to be in the range of 19-23 nm. These sizes of integrated CuO nanoparticles is a cost-efficient, biological molecule capable of working with antibiotics against Staphylococcus saprophyticus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli.
