Study on the Property of Silica Minerals Supported Nano-TiO2
In the study,porous amorphous silica minerals including Porous Silicon(PS),Diatomite Filter Aid(DFA) and Opal(Op) were chosen as carriers or supports to prepare TiO2/PS,TiO2/DFA and TiO2/Op composites by chemical co-precipitation method.The compound materials were characterized by SEM,TEM,and the photo-catalytic property of the prepared composites was investigated by degradation of Rhodamine B (RhB).Characterization showed that nano-TiO2 was coated on the surface of porous amorphous silica minerals.The crystal form of TiO2 was mainly anatase,and the size of which was nano-scale.Through comparative analysis,the photo-catalytic efficiency of TiO2/PS composite was the best,followed by TiO2/ DFA,and then TiO2/Op.
