摘要
采用溶胶-凝胶法制备了纳米TiO_2光催化剂及其稀土离子掺杂改性的产物,经XRD和SEM表征、光催化活性评价对比分析后,结果表明:稀土离子掺杂摩尔分数为0．5%时,光催化活性最高。
TiO2 and cerium oxide promoted TiO2 were prepared by a sol-gel method, characterized by XRD and SEM, and studied in a photocatalytic oxidation reaction. The results showed that promotion by cerium oxide increased the catalytic activity and the optimal loading of cerium oxide was 0.5 mol%.
