Complete Toluene Oxidation over Palladium-Based Monolithic Catalyst Prepared via a New Electroless Plating Method

Abstract:

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.
