Platinum catalysts gold addition effect

Recently, it has been shown that CeOg-ZrOg is a very effective support for noble metals. A comparative study of WGS reactions over gold and platinum supported on ZrOg and Ce02-Zr02was carried out by Boaro et aV It was found that at lower temperatures gold catalysts were more active than platinum ones. The addition of zirconia to ceria leads to a modification of the redox and structural characteristics of the supports and this affects the activity of these catalysts. [Pg.537]
