We investigated the catalytic behaviour of La2O3 catalysts with different spatial dimensionality, such as zero-, one-, two-and three-dimensional structure, for the oxidative coupling of methane. The La2O3 catalyst with two-dimensional structure exhibited the highest conversion of methane with the most ethylene and ethane produced among these catalysts. The collective contribution from the exposed specific facets, more electron deficient oxygen species and more moderate surface basic sites on the two-dimensional La2O3 catalyst account for its highly efficient catalysis in the oxidative coupling of methane to produce ethylene and ethane.
