查询词典 acetylene

Furthermore,the adsorption of acetylene on the Ni(111)surface is investigatedby DV-Xα method,as well as its migration pathway from the aligned bridgesite,the favorite adsorption site for ethylene,to the cross-bridge site.Afterstudying several reaction pathways of C2H2 on Ni(111),we find that acetylene,as the product of dehydrogenated ethylene,will migrate from the alignedbridge site to the cross-bridge site with a very small energy barrier,0.02eV.

给出了乙炔在各个吸附位的吸附结构，并在假定乙烯在脱氢前没有迁移的基础上，对各种可能的反应途径作了模拟研究，发现乙炔在平行桥位的吸附结构不稳定，通过1.24的平移和30度的旋转的耦合，迁移到垂直桥位，迁移过程中只有0.02eV的势垒。
