Abstract

We found that LaInO 3 perovskite catalyst showed high activity for oxidative coupling of methane (OCM). Partial substitution of La 3+ site in the LaInO 3 catalyst with Ba 2+ increased its catalytic activity and selectivity to C2 hydrocarbons drastically. The partial substitution of La 3+ site in LaInO 3 with Ba 2+ increased oxygen vacancies in the stable cubic phase, and then contributed to the production of active oxygen species on its surface for selective C2 formation.
