The C2 selectivity of catalyst La2O3 in oxidative coupling of methane may be increased by doping small amount of CaO. Some experimental techniques were adopted such as measurement of fluorescence emission of Eu3+ doped into La2O3, determinations of the lattice parameters and XPS of the catalysts. The doping of CaO results in an increase in ambient symmetry of La3+ and in the concentration for creating oxygen ion vacancies in La2O3.
