Meso-macro-porous monolithic Pt-Ni/Al2O3 catalysts used for miniaturizing preferential carbon monoxide oxidation reactor

Meso-macro-porous monolithic Pt-Ni/Al2O3 catalysts with platinum and nickel in interaction and in a highly dispersed state have been successfully prepared, and the obtained catalysts are highly efficient for CO removal from hydrogen rich gases via preferential oxidation; the results show that preparing catalysts to meso-macro-porous monolithic structure is a promising way for the miniaturization of CO removing reactor.
