摘要: Three types of carbon species were found on Rh supported on Al2O3, Rh crystals and support over Rh/Al2O3, respectively. On CeO2-promoted Rh/Al2O3, the presence of Rh-CeO2 interface increased both the amount and reactivity of the carbon formed on Rh supported on Al2O3, which was involved in CO formation mechanism of reforming reaction. The much lower amount of the carbon deposited on Rh particles was observed that was most likely responsible for the deactivation of catalyst, with greatly suppressed graphitic carbon deposition on support. A schematic model of carbon deposition over Rh-CeO2/Al2O3 was proposed.
