| Abstract: | Using TiO2 powders as precursor,the TiO2 nanometer fiber was prepared by hydrothermal reaction.The structure of the product was analyzed by SEM,XRD and IR.photocatalysis.The degradation performance of the synthetic product on Congo red was investigated.The results showed that the product was anatase TiO2 with good crystallization,and the degradation rate of Congo red by TiO2 powder and fibers were 89.1% and 97.4%,respectively. |
