摘要：
Pd/CeO2 and Pd/Zr-CeO2 diesel oxidation catalysts were treated with sulphur, sulphur–water and water. According to the BET, TEM-EDS, XPS, ICP-OES analyses and catalytic activity tests, both studied catalysts were deactivated by sulphur due to formation of sulphates. Water treatment was found to have a promoting effect on the oxidation of CO and C3H6.
