摘要
以TiCl4和La2O3为原料,海泡石为载体,采用过氧化氢络合物热分解法制得复合TiO2/La2O3/海泡石光催化剂.以罗丹明B为目标降解物,进行正交试验,研究得到制备的最佳条件.探讨了对甲基橙溶液的降解率的影响因素.在优化实验条件下,太阳光照150 min时,该光催化剂对罗丹明B的降解率达98%.
The methods for preparation of TiO2/La2O3/sepiolite composite materials using the titanium tetraehloride solution and lanthanum oxide as the raw materials and the natural sepiolite as the carrier by means of H2O2 complex hydrolystic precipitation are researched. The best condition of deeolorization for Rhodamine B solutions have be obtain by studying on orthogonal design. And the factors of influence on the rate of photocatalysis degradation for Rhodamine B solution is investigated. In optimum process, the rate of photoeatalysis degradation of the Rhodamine B is 98% under the sunlight for 150 min.
