The Ru(0001) surface exhibited a strongly affinity for oxygen which gave preference to form a (22)-O phase. However, anodization of Ru(0001) electrode produced a (11)-O phase. A coadsorption structure (2CO+O)(22) / Ru(0001) was performed from electrosorption of CO on Ru(0001) surface in electrolyte solution.展开更多
