| Abstract: | The methods for preparation of TiO_2/La_2O_3/sepiolite composite materials using the titanium tetrachloride solution and lanthanum oxide as the raw materials and the natural sepiolite as the carrier by means of H_2O_2 complex hydrolystic precipitation are researched.The best condition of decolorization 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 photocatalysis degradation of the Rhodamine B is 98% under the sunlight for 150 min. |
