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.
