We investigated four catalytic reactions assisted with in electric field to promote catalytic activity, and we could achieve an effective process for hydrogen production at low temperatures. Such as 423 K. In the presence of the electric field, four reactions of steam reforming of ethanol, decomposition of ethanol, water gas shift, and steam reforming of methane proceeded at very low temperature, Such as 423 K, where a conventional catalytic reaction hardly proceeded. Conversion of reactant was greatly increased by the electric field, Zinc apparent activation energies for these four reactions were lowered by the application of the electric field. This process cart produce hydrogen and syngas by using a considerably small energy demand and has quick response.
