A method for selectively oxygenating methane to carbon monoxide and hydrogen by bringing the reactant gas mixture at a temperature of at least 600 DEG C. into contact with a sold 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. |
