Abstract

We found that methane was selectively oxidized by water to give C₂ hydrocarbons and hydrogen on ATi_1-xB_xO_3-δ (A = Sr, Ba, B = Mg, Ca). The coupling activity and selectivity on SrTi₀₄Mg₀₆O_3-δ in the presence of steam was 95%, which was much higher than that on pure SrTiO₃. This suggests that the selective oxidative coupling of methane by water was catalyzed by the oxide ion defects on ATi_1-xB_xO_3-δ (A = Sr, Ba, B = Mg, Ca).
