摘要：

Palladium nano-particles in 2 wt% Pd/ZrO2 prepared by the deposition-precipitation method interact strongly with zirconium oxide. The catalyst is significantly active to the methanol decomposition to carbon monoxide and hydrogen at less than 500 K with the apparent activation energy of ca. 80 kJ mol(-1) compared with 2 wt% Pd/ZrO2 prepared by the impregnation technique which produces the activation energy of ca. 100 kJ mol(-1).
