PURPOSE:To obtain an ethanol reforming catalyst developing high activity and high selectivity at a low temp., free from carbon precipitation and having long life, by allowing a carrier containing rutile type titania to support one or more of a metal selected from a group consisting of platinum and Pd. CONSTITUTION:A rutile type titania-containing carrier is allowed to support one or more of a metal selected from a group consisting of platinum and Pd. The above mentioned carrier is easily obtained by baking anatase type titania or one prepared by coating alumina with titania at 600 deg.C or more. In the next step, the noble metal is supported by the carrier according to such a method that the carrier is immersed in an aqueous solution containing a compound, for example, a noble metal nitrate and, after baking, the baked supported carrier is further subjected to hydrogen reducing treatment. Thus obtained catalyst is excellent in reaction for reforming ethanol to gas containing H and CO and shows high activity and high selectivity at a low temp., for example, at 300 deg.C while prevented from carbon precipitation and develops long life.
