摘　　要：用传统的溶胶-凝胶法、改进的溶胶-水热法制备了纳米TiO2和掺杂纳米TiO2,通过对甲基橙有机废水的光催化降解模拟实验,比较不同产品的光催化性能,发现改进的溶胶-水热法优于传统的溶胶-凝胶法,掺杂纳米TiO2优于纯纳米TiO2.Nanometer-sized TiO2 and doped nanometer-sized TiO2 was synthesized via the sol-gel method or sol-hydmthermal method. All samples photocatalytic activity was investigated by model reaction, the photocatalytic degradation of methyl orange. The results showed that the improved sol-hydmthennal method is better than the solgel method. Doped nanometer-sized TiO2 is better than pure nanometer-sized TiO2.
