Study on Photocatalytic Properties of TiO2 by Sol-gel

摘要：

　　In order to further enhance the TiO2 photocatalyst activeness,this research uses the non-metallic ion doping to modify TiO2.In this study,selected nonmetal B has prepared the doping modification TiO2 by using the sol-gel method.Ti (OC4H9)4 is the source of titanium,C2H5OH is the solvent.Under the same conditions,considered the reagent ratio,roasting temperature and roasting time how to influence the crystal composition,the particle size and the catalytic activity.And uses XRD to study the phase transition of the TiO2 powder body in the roasting process,inspect the influence of various nonmetallic ion boron doping to crystal structure and size of the TiO2 powder body.Through the degradation magenta solution,has studied boron to the titanium dioxide photocatalytic activity,has determined the reagent ratio,sintering time,sintering temperature and the doping quantity.
