Abstract

A series of Pt/Fe co-loaded mesoporous zeolite beta (Pt/Fe–mBeta) catalysts with different Fe contents have been successfully synthesized by an ion exchange and subsequent ethylene glycol reduction method. The catalysts were characterized by XRD, N2 adsorption–desorption, TEM, SEM, XPS and H2-TPR. The optimized sample Pt/Fe(3)–mBeta shows high catalytic activity for CO oxidation under dry conditions, and the complete conversion temperature of CO is as low as 90 °C. More importantly, the sample Pt/Fe(3)–mBeta also shows excellent water resistance and good durability, which could meet the practical needs of exhaust purification of diesel vehicles. It is believed that the synergistic effect between varied-valence Pt/Fe species and the mesoporous zeolite support with high surface area and good water resistance jointly contribute to the excellent catalytic performance.
