| 摘 要： | XPS和UPS研究结果表明,在金属镁表面氧化过程中存在的过渡态氧O~(δ-)对甲烷有很强的脱氢活性,生成CH_x(x=1,2,3)和深度氧化吸附态CO_3~(2-),以质谱和色谱研究结果表明,CHx偶联生成乙烷和乙烯,CO_3~(2-)热分解生成CO和CO_?。

| Abstract: | The reaction of oxidative coupling of methane to ethane and ethylene on magresium surfaces had been studied by Photoelectron Spectros copy. Mass pochoneter ard Gas Chronatograpby. The experimental results indicated that O8- (a) produced on magnesium surface has strong ability for methane dehydrogenation. The generated CH(?) (a) dimerized on the surface or in the gaa phase to form ethane and ethylene. Complete oxidation of meth-ane to CO ( g ) , CO2(g) and CO(?) (a) was also observed. |
