Abstract

Pulse reaction showed that Co/Al₂O₃ catalyst was active for the high-temperature decomposition of CH₄ and CO₂. CH₄ mainly was completely decomposed to give surface carbon, which could be inactivated quickly in the absence of enough O_(ad) (arising from dissociation of CO₂). CO₂ was dissodatively adsorbed on Co(0) sites to give CO_(ad) and O_(ad), which was a slow step. Further decomposition of CO_(ad) happened in the case of CO₂ decomposition.
