Preparation and Photocatalytic Activity of Mo-doped TiO2/AC Immobilized Membranes
Abstract:
Mo-doped TiO2/AC immobilized membranes were formed on the surface of active carbon (AC) by a solgel method from ammonium molybdate and tetrabutylorthotitanate and characterized by UV-Vis spectrophotometry,TEM and XRD.The photocatalytic activities of the immobilized membranes were evaluated in photodegradation of methyl orange and omethoate aqueous solutions,respectively.The results show that both the rutile phase and anatase phase are formed in Mo-doped TiO2/AC immobilized membranes,but only rutile phase in the un-doped TiO2/AC immobilized membrane.The band edges in diffuse reflectance UV-Vis spectra of the Mo-doped TiO2/AC immobilized membranes show a red shift as compared with that of the un-doped membrane.The immobilized membrane shows the highest photocatalytic activity when mass fraction of Mo in TiO2 is 1.5%.
