Abstract

We found that methane was selectively oxidized by water to give C2 hydrocarbons and hydrogen on ATi1-xBxO3-δ (A = Sr, Ba, B = Mg, Ca). The coupling activity and selectivity on SrTi04Mg06O3-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 ATi1-xBxO3-δ (A = Sr, Ba, B = Mg, Ca).
