Preparation and Three-Way Catalytic Performance of Cu-Ce-Zr-O Mixed Oxide Catalysts

Abstract

Abstract: A mixed oxide three-way catalyst Cu-Ce-Zr-O, which could efficiently purify the automobile exhaust, was prepared using non-precious metal. Under lean-bu rn conditions (air/fuel ratio of 1.33), the catalyst showed better three-way c a talytic performance. The light-off temperatures for CO, C3H6, and NO were 1 83, 257, and 236 ℃, respectively; and the complete conversion temperatures for the t hree gases were 197, 340, and 286 ℃, respectively. At low working temperature, NO, CO, and C3H6 could be converted into innoxious gases.

Key words: copper, ceria, zirconia, mixed oxide, three-way catalyst, sol-gel method
