A method for selectively oxygenating methane to carbon monoxide and hydrogen by bringing the reactant gas mixture at a temperature of at least 600.degree.C into contact with a sole catalyst which is either; a) a catalyst of the formula MxM'yOz where: M is at least one element selected from Mg, B, Al, Ln, Ga, Si, Ti, Zr and Hf, Ln is at least one member of lanthanum and the lanthanide series of elements, M' is a d-block transition metal, and each of the ratios x/z and y/z and (x+y)/z is independently from 0.1 to 8; or b) an oxide of a d-block transition metal; or c) a d-block transition metal on a refractory support; or d) a catalyst formed by heating a) or b) under the conditions of the reaction or under non-oxidizing conditions. |
