摘要：
Methane activation was conducted on Pt, Pd, Ru and Rh alumina supported catalysts. Simultaneously with the gas chemisorption, H-2, CO2 and CO were evolved from all the catalyst surfaces. The H-2 evolution resulted from the association of hydrogen atoms provided from dissociative chemisorption of methane. CO and CO2, evolution was explained by the partial migration of carbon adspecies, from metal surface to the metal-support interface, followed by their interaction with the alumina O2- ions.
