摘要:以TiO2粉体为前驱体,用水热法制备了TiO2纳米纤维,用扫描电镜、x-衍射和红外光谱对产物进行了表征,考查了合成产物对刚果红溶液的光催化降解性能.结果表明:合成产物属锐钛矿相TiO2,产物结晶完好;TiO2粉体和纤维对刚果红水溶液的降解率分别为89.1%和97.4%.

关键词: 二氧化钛, 水热法, 纤维, 光催化

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.

Key words: TiO2, hydrothermal method, fiber, photocatalysis
