Microwave (MW)-enhanced catalysis is a promising research area that is quickly gaining interest for a wide-range of chemical reactions. Most traditional heterogeneous catalysts are based on metal oxides supported with dispersed metallic particles which do not always heat and respond to the electromagnetic field used in the microwave reactors. Therefore, catalyst design must be optimized to maximize the field interaction with the catalyst. A series of materials typically used for fuel cells like doped-ceria and -zirconia, and perovskite lanthanum with and without metallic particles were investigated for their catalytic properties for methane conversion under traditional thermal and MW methods. Generally the materials were not active for methane conversion under traditional methods, at the reaction conditions studied, while the microwave reactor usually provided a complete conversion for some of the material used. Under microwave conditions, the selectivity of methane conversion varied, and the characterization of these catalyst will be discussed.
