Received Date: 16 January 1993

The MOC reaction over ZrO₂/LaF₃, CeO₂/LaF₃ and ThO₂/LaF₃ catalysts indicated hat these catalysts had high activity and high C₂ selectivity at low temperature.In the temperature range 480℃ to 650℃.The methane conversion was 24.4% to 30.8%and the C₂ selectivity was 40.0% to 55.4%.The XRD characterization of the catalysts indicated that O^2-.and F^- exchang happened and LaOF was formed.
