Abstract

Abstract: The C₂selectivity of catalyst La₂O₃for oxidative coupling of methane may be enhanced by doping a small amount of CaO. The studying results by using some experimental techniques, such as determination of ionic conductivity, determination of lattice parameters, Raman spectroscopy and XPS of the catalysts indicated that part of La³⁺ions was substituted by Ca²⁺ion(≤3 mol%) in La₂O₃lattice and C₂selectivity in OCM reaction was increased due to the formation of O^-ions.

Key words: Rare earth, Oxidative coupling of methane, La₂O₃catalysts
