The catalyst may be used to obtain hydrogen or synthesis gas for chemical industry in processes of partial oxidation, steam reforming, and autothermal reforming of a hydrocarbon feed. The catalyst of oxidative conversion of gaseous hydrocarbons to form carbon monoxide and hydrogen contains platinum-group metals and an oxide composition and characterized in that the platinum-group metals include Pt, Pd, and Rh and the oxide composition is obtained from a mixture of a sol of Al, Si, and Zr hydroxides with particles of Ni, Mg and/or Ce oxides with a size of 5-30 nm, that were obtained by spray-pyrolysis of a solution of Ni, Mg and/or Ce salts.
