Abstract
The present invention is a hydrogen combustion catalyst including a catalyst metal supported on a carrier composed of an inorganic oxide, wherein a functional group having at the end thereof at least an alkyl group having three or less carbon atoms is bonded by substitution to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier. The functional group bonded to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier is preferably an organic silane. The hydrogen combustion catalyst according to the present invention is capable of maintaining the activity thereof even when a hydrogen-containing gas, a treatment object, contains a water content equal to or less than the saturated water vapor content and the reaction temperature is set at or around room temperature, namely, at 0 to 40° C.
