| Abstract: | TiO2/SiO2 composite materials were prepared by hydrolysis method of TiCl4 and super-fine quartz powder.It was founded that TiO2 was bonded to SiO2,and formed a Si—O—Ti network structure by IR.The structure of composite materials was anatase-phase crystal structure by XRD and the particles had a certain agglomeration by TEM.The degradation of methyl orange was tested by photocatalysis of the TiO2/SiO2 composite materials.The results indicated that the degradation rate of methyl orange was 69% with 120min. |
