Abstract:
The ethylene(C2H4)absorbs in molecular state on Ru (1010) surface stably below 200K. The dehydrogenated of ethylene occurs at 200K. The main product of the dehydrogenation of the absorbed ethylene is the acetylene (C2H2). After the dehydrogenation of the absorbed ethylene, the binding energies ofσCCandσCHbond have an increase of 0.5 and 1.1eV respectively. The C-C bonds of both ethylene and acetylene tilt in <0001> azimuth.
Key words:  Ethylene, Dehydrogenated, Valence band, Ru(1010)

摘要:
在200K以下乙烯(C2H4)可以在Ru(1010)表面上以分子状态稳定吸附,200K以上乙烯发生了脱氢分解反应生成乙炔(C2H2).乙烯分解生成乙炔后,σCC和σCH分子轨道能级向高结合能方向分别移动了0.5和1.1eV.偏振角分辨紫外光电子谱(ARUPS)结果表明:在Ru(1010)表面上,乙烯和脱氢反应后生成的乙炔分子的C-C键轴都不平行于表面,而是沿表面(0001)晶向倾斜.
