The OCM reaction was studied on BaF₂-LaOF catalyst and the results show that CH₄ can be effectively activated and selectively converted to C₂⁺.Under the reaction conditions of GHSV=15000h^-1 and reaction temperature 1044K, the high C₂⁺ yield of 20.66% with CH₄, conversion of 33.08% and C₂⁺ selectivity of 62.47% was obtained at CH₄:O₂=3:1, and the high C₂⁺ selectivity of 84.55% with CH₄ conversion of 16.54% was obtained at CH₄:O₂=9:1.XRD results suggest that tetragonal LaOF is the active phase in BaF₂-LaOF catalyst.
