Abstract

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the increase of TiO2loading. Scanning electron micrographs of synthesized samples show that nano size titanium dioxide particles are accumulated on the surface of the zeolite. These materials are applied as photo catalysts for the degradation of orange G in aqueous solution by means of ultraviolet light irradiation at room temperature. The effect of solution pH, ultraviolet irradiation time and catalyst in degradation of orange G was investigated. The results show that nickel doped TiO2/NaX zeolite as a photo catalyst in degradation of orange G in acidic solution is superior to the Ni/TiO2 nano composite and also undoped nano size titanium dioxide particles.
