Sonosynthesis and Characterization of TiO2/ZrO2 Nanocomposite and Photocatalytic degradation of Congo red Dye under UV Light
NanoTiO2 nanoZrO2 and TiO2 /ZrO2 nanocomposite were prepared via sol gel method by using ultrasonic irradiation. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4 and titanium tetra 2 propoxide was diluted by 2 propanol and deionized water The TiO2 /ZrO2 nanocomposite was synthesized from directly mixing Titanium dried gel into Zirconium gel. The reaction mixture was placed under ultrasonic irradiation probe for 2 hours. The filtrated composite gel was washed and calcinated at 500 degC for 3h in furnace. The FT IR spectroscopy and the XRD study were exhibited that the crystal structure and purity of the TiO2 /ZrO2 nano composite FESEM images were indicated the morphology and the average size of the NPs. The mean crystallite size of the NanoTiO2 nanoZrO2 and TiO2 /ZrO2 nanocomposite were determined 57, 19 and 23 nm respectively. The photocatalytic performance was highly increased when nano composite of TiO2 /ZrO2 was used to degradation of Congo red (CR) solution. The TiO2 /ZrO2 nano composite was shown higher photo degradation efficiency than the pure nanoTiO2 and nanoZrO2
