preparation and characterization of zro2/zno nanocomposite under ultrasonic irradiation via sol-gel route

nanocomposite of zro2/zno was prepared under ultrasonic irradiation by sol gel process from directly mixing zirconium and zinc gels, and the mixture was placed under ultrasonic irradiation for 2 hours then aging time the filtrated composite gel was calcinated at 500°c for 3h in furnace. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4 and zinc acetate dihydrated was dissolved in de-ionized water. the ft-ir analysis and the xrd study were exhibited that the crystal structure and purity of the zro2/zno nanocomposite fesem images was indicated the morphology and the average size of the nps. the average size of the zro2/zno nanocomposite was determined 37 nm.
