TiO_2对RuO_x的载体的催化作用

EFFECT OF TIO_2 AS CARRIER ON THE CATALYSOIS ACTlVATION OF RuO_x

以ＴＰＲ、ＴＧＡ、ＣＯ滴定方法对ＴｉＯ＿２、Ａｌ＿２Ｏ＿３为载体的ＲｕＯ＿ｘ氧化还原催化剂进行对比研究。结果表明以ＴｉＯ＿２为载体，可以降低ＲｕＯ＿ｘ的还原峰温，提高ＲｕＯ＿ｘ中氧的活性，降低ＣＯ与ＲｕＯ＿ｘ的反应活化能．它对于研究高活氧化还原催化剂提供了一定的有用信息，文中对ＴｉＯ＿２的作用机理也进行了探讨。

By using TPR,TGA and CO titration method, it is foud that the RuO_x supported onTiO_2 have higher rcactive activation than supported on Al_2O_3.The RuO_x on TiO_2 have lower tempera-ture poak of TPR reduction and lower active energe of reaction with CO,It is obviously that the oxgenof RuO_x on TiO_2 have higher reactive activation. The possibic effective mecharusm of TiO_2 is discussedas.Well.
