A catalytic process is disclosed for oxidizing cycloalkanes directly to form, in a single step, a mixture containing the corresponding alcohol and ketone. In particular, the invention relates to oxidizing a cycloalkane by contacting it with a source of oxygen and a catalytic amount of a heterogeneous catalyst. The catalysts of the invention include gold (including gold sol-gel compounds) and sol-gel compounds containing particular combinations of Cr, Co, Zr, Ta, Si, Mg, Nb, Al and Ti, wherein certain of those metals have been combined with an oxide, such as an inorganic matrix of hydroxides or oxides, or combinations thereof. The catalysts may also optionally be supported on a suitable support member.
