Surface-structure-dependent reaction pathways of methyl groups on ni(100) and Ni(111) surfaces

摘要

Reactions of hydrocarbon fragments such as methyl groups on transition metal surfaces play an important role in a number of catalytic processes, including oxidative coupling of methane, methanation of syngas, steam reforming, and partial oxidation of methane to syngas. Although important, our knowledge of the fundamental mechanisms and kinetics of their reactions is limited.
