摘要：A facile one-pot co-precipitation approach was applied to fabricate a meso-structured Pd-CeOx composite for low temperature CO oxidation. The as-prepared material had a much higher specific area and highly dispersed noble metal species, and thus showed excellent catalytic activity and stability for CO oxidation, especially under ambient conditions. Complete CO conversion could be achieved at as low as 25 degrees C for 5.9 wt% Pd doped catalyst, when 3.0 vol% H2O was introduced into the feed gas. The reaction mechanism on such a catalyst has been proposed through in situ DRIFTS and kinetic analysis.
