The palladium-based catalyst of 0.36wt%Pd/cordierite honeycomb ceramics (CHC) without alumina interlayer film was prepared via a new electroless plating method. The results of activity test for complete toluene oxidation showed that the prepared catalysts had good catalytic activity and temperature resistance. The total oxidation temperature (T99) for toluene was at 230°C for the catalyst calcined at 500°C. The scanning electron microscopy (SEM) results indicated that the particles of palladium phases were small and well dispersed on the CHC substrate surface. And the X-ray photoelectron spectrum (XPS) further revealed that both PdO state and adsorbed oxygen species participated and played a more important role in toluene oxidation reaction.
