稀土元素对磷钼钒杂多酸催化氧化活性的影响

The Effect of Rare-Earth on Oxidization Catalyzed by Heteropoly Molybdovanadophosphoric Acid

讨论了镧的置換度和稀土元素对含氧有机化合物在杂多酸催化剂上的氧化反应的影响,并与催化剂的结构进行了关联。镧的引入不影响氧化脱氢反应,而明显削弱插入氧反应。其它稀土元素的影响与镧相同。

The effect of the substitution extent of lanthanum and other rare-earth elements on oxidation reations of oxygen-containing organic compounds over heteropoly acid catalysts and the reactivity to correlate with structure of the catalysts are discussed. The addition of lanthanum does not change the activity of oxidative dehydrogenation, but lowers that of oxygen-addition reation apparently.
