This invention relates to a method for the oxidative conversion of methane to ethylene and/or ethane and to a catalyst system for use in the method. In more detail a method for the oxidative conversion of methane to ethylene and/or ethane in which a mixture comprising methane and oxygen is heated to a temperature of from 500.degree. to 1000.degree. C. and the heated mixture is contacted with a catalyst system which comprises a first component which is a non-reducible metal compound and which first component is sufficiently refractory to withstand the operative temperature and a second component which is one or more oxycompounds of boron or phosphorus provided on the surface of the first component.
