| 摘 要： | 用溶胶-凝胶法制备了V-N-TiO2/凹凸棒土光催化复合材料，研究了V-N-TiO2/凹凸棒土的制备方法、V-N-TiO2与凹凸棒土的质量比、煅烧温度和煅烧时间对V-N-TiO2/凹凸棒土光催化性能的影响。在模拟太阳光条件下，以亚甲基蓝溶液为目标降解物，对V-N-TiO2/凹凸棒土光催化性能进行测定。研究结果表明：当V-N-TiO2与凹凸棒的质量比为1：3、煅烧温度为300℃和煅烧时间为2 h时，得到的V-N-TiO2/凹凸棒土光催化复合材料对亚甲基蓝的光催化性能最佳。

| Abstract: | V-N co-doped TiO2/attapulgite photocatalytic composite materials were synthesized by slo-gel method, preparation method, V-N-TiO2 and attapulgite of mass ratio, calcination temperature and time of V-N-TiO2/attapulgite on photocatalytic properties were studied. On the condition of simulative sunlight, photocatalytic properties of V-N-TiO2/attapulgite were measured by using methylene blue as evaluation standards. Research shows that when mass ratio of TiO2 to attapulgite is 1：3, calcination temperature is 300℃ and calcination time is 2 h, the best performance properties of V-N-TiO2/attapulgite photocatalytic composite materials to methylene blue is obtained. |
