摘要: We report experimental evidence for the formation of a ‘‘subsurface’’ hydrogen species at 130 K on Pd(110) single crystal surface. This is well separated by distinct activation energy barriers from which are chemisorbed or dissolved in Pd bulk, thereby confirming model H absorption subsurface state acts as reaction intermediate.
