Carbon Oxidation Reaction over Pt/Spherical Alumina Beads Catalysts Prepared by Sputtering Method

Pt catalysts supported on Al2O3 beads prepared by a sputter deposition method showed the higher surface concentration of Pt than impregnated Pt catalysts. The catalytic activities of the oxidation of acetylene carbon black over the sputtered Pt catalysts were higher than those over the impregnated Pt catalysts with the same Pt content.
