| Abstract: | 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. |
