Abstract

It was found that the adsorbed oxygen on perovskite type oxide (SrTi1-xMgxO3-δ) which carry oxide ion defects could oxidize methane to C2 hydrocarbons very selectively at around 660 K. On this type of oxide, gaseous oxygen exchanged with bulk oxide ion easily at 500-600 K, which SrTiO3 showed very low activity for this reaction. Adsorbed oxygen was found to be O22- state below 600 K.
