摘要
以TiCl_4和Y_2O_3为原料,海泡石为载体,采用过氧化氢络合物热分解法制备了复合TiO_2/Y_2O_3/海泡石光催化剂.以甲基橙为目标降解物.进行正交试验,得出制备的最佳条件.研究了对甲基橙溶液的降解率的影响因素。
The methods for preparation of TiO2/Y2O3/sepiohte composite materials using the titanium tetrachloride solution and yttrium 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 decolofization for methyl orange solutions have be obtain by studying on orthogonal design. And the factors of influence on the rate of photoeatalysis degradation for methyl orange solution is investigated.
