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.
