Abstract

A series of CeZr/FAU zeolite membranes with different Ce/Zr doping ratios was prepared by impregnation method，and further loaded with nano-gold to prepare Au-CeZr/FAU catalytic membranes. The obtained membranes were well characterized，and their catalytic performances toward the preferential oxidation of CO in H₂-rich gases were studied. The H₂-TPR analysis showed that the Au-Ce₁Zr₁/FAU membrane with Ce/Zr doping ratio of 1∶1 had the best redox ability，which benefited the dispersion and reduction of Au nanoparticles. The O₂-TPD analysis suggested that this membrane also possessed more active oxygen species. As a result，the Au-Ce₁Zr₁/FAU catalytic membrane exhibited the best catalytic activity for CO-PROX reaction with 100% CO conversion and 100% O₂ selectivity at low temperature of 60 ℃ as well as high stability for 10 thermal cycling tests.
