| Abstract: | Nanometer TiO_(2)-SiO_(2) composite photo-catalyst is prepared by hydrolysis with boiling reflux from Na_(2)SiO_(3) and (Ti(SO_(4))_(2),)which are as raw materials.The optimum preparing conditions of the TiO_2-SiO_2 composite photo-catalyst are discussed and the specimen is characterized by XRD,XPS,TEM and BET.The results show that the TiO_(2)-SiO_(2 )particles obtained are spherical and their sizes are about 10 nm,they are composed of anatase TiO_(2 ) and amorphous SiO_(2). |
