Oxidative coupling of methane by water as the oxidant on perovskite oxide catalysts

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 SrTi0.4Mg0.6O3−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).
