| 摘 要： | 以活性炭(AC)为载体,通过溶胶-凝胶法制备了Fe3+离子掺杂的TiO2/活性炭(Fe3+-TiO2/AC)负载型光催化剂,通过SEM、XRD、UV-Vis等手段对光催化剂进行了表征。以125W高压汞灯作为光源,通过对罗丹明B的光降解反应,主要考察了温度对Fe3+-TiO2/AC复合体的光催化活性的影响。结果表明,温度在600℃条件下焙烧的Fe3(+0.15%)-TiO2/AC具有最好的光催化活性。

| Abstract: | Complex photocatalyst of Fe3+-doped nano-sized titanium dioxide was prepared by sol-gel process via the carrier of activated carbon.As-prepared catalyst was then characterized by SEM,XRD and UV-Vis for detailed morphology,crystallization and optic property respectively.Photocatalytic activity of Fe3+-TiO2/AC was investigated by degradation reaction of Rhodamine B radiated with mercury lamp as light source.Effects of heat treatment temperature on photoactivity of Fe3+-TiO2/AC were studied.Results showed that... |
