前文报道了CO与Pr_6O_(11)表面反应的结果.已发表的关于烃类与氧化物表面反应的研究,旨在了解烃类的活化和表面氧化机理,而且大部分工作都是在过渡金属氧化物上进行的.近年来的研究表明,稀土氧化物将是有潜力的甲烷氧化偶联制乙烯的催化剂,在消除环境污染的烃类完全氧化催化剂中,稀土氧化物也常被用作助剂或活性组分,但对于稀土氧化物本身的催化表面研究尚不多见.作者曾较系统地研究了CeO_2的表面催化性质,发现表面上存在多种氧物种,这些氧物种与烃类的反应活性差异很
The results reported above for the reaction of CO with Pr 6 O 11 surface have been reported.Researches on the surface reactions between hydrocarbons and oxides have been published to understand the mechanism of activation and surface oxidation of hydrocarbons and most of the work is focused on the transition metal oxidation In recent years, studies have shown that rare earth oxides will be potential catalysts for the methane oxidation of ethylene, in the elimination of environmental pollution of hydrocarbon complete oxidation catalyst, rare earth oxides are often used as additives Or active component, but the rare earth oxide itself, the catalytic surface research is rare.We have systematically studied the catalytic properties of CeO 2 surface and found that there are many oxygen species on the surface of these oxygen species and hydrocarbon reaction Very different activity
