Hydrogen combustion catalyst and method for producing thereof and method for combusting hydrogen

摘要

The present invention relates to a hydrogen combustion catalyst in which a catalyst metal is supported on a carrier composed of an inorganic oxide, wherein a hydroxyl group on the surface of the carrier is substituted with a functional group having at least one alkyl group having 3 or less carbonic acid Wherein the catalyst is a hydrogen combustion catalyst. The functional group bonding to the hydroxyl group on the surface of the support is preferably an organosilane. In the hydrogen combustion catalyst of the present invention, the hydrogen-containing gas to be treated contains water having a saturated water vapor amount or less and can maintain its activity even at about room temperature at 0 to 40 ° C.
