Abstract: Attapulgite loaded zinc oxide-titania (ATP/ZnO-TiO₂）nano composite material was prepared by chemical precipitation method with TiOSO4,ZnSO₄,and (NH4)₂CO₃ as raw materials and ATP as carrier.Samples were characterized by XRD and TEM.Photocatalytic activities were evaluated by degradation of activeness scarlet (BES) and the conditions for preparing this composite material were optimized.Results showed that the optimum conditions for preparation of the nano composite material were as follows:mass ratio of ATP to TiO₂ was 20%,amount substance ratio of TiO₂ to ZnO was 10 ∶1,and calcined temperature was 450 ℃.Under these conditions,the effect of photocatalytic activity of the composite material to BES was the best.Compared with ATP/TiO₂ and ATP/ZnO,the nano composite material had better photocatalytic material performance under visible light.
