The synthesis of high surface area carbide and nitride materials from binary and ternary oxides of vanadium, niobium, tantalum, molybdenum, and tungsten, suitable for use as catalysts for a wide range of reactions, has been investigated via the temperature-programmed reaction (TPRe) method, in various gas mixtures. TPRe of oxides in CH{sub 4}/H{sub 2}, C{sub 2}H{sub 6}/H{sub 2}, or NH{sub 3} yield materials with surface areas > 40 m{sup 2}/g. For the reaction with ethane or ammonia the reaction appears to proceed topotactically while that with methane does not; however, the conversion of nitrides to carbides in CH{sub 4}/H{sub 2} does appear to proceed topotactically.
