Pd/LaFeO3/Al2O3 catalysts were prepared by co-deposition of Pd and LaFeO3 perovskite oxides in the intrapores of Al2O3 by the incipient wetness method. Pd and LaFeO3 perovskite oxides were highly dispersed on Al2O3 in the inside pore. H2-TPR studies revealed that the oxidation state, dispersion and redox properties of Pd were affected by the presence of LaFeO3 with close proximity. The Pd and LaFeO3 co-deposited Al2O3 catalysts exhibited much higher activity for CO oxidation and NO–CO reaction than Pd/Al2O3 catalysts.
