摘要： 由于催化燃烧比传统的热力燃烧法有反应温度低和能量消耗低的优点,因而广泛用于挥 发性有机物和CO的消除.钯和铂是最常用的催化剂,但是载体对催化性能的影响很大[1,2].本文制备了系列负载钯催化剂,发现载体的性质对催化剂的CO氧化活性影响很大.

关键词: 负载PdO催化剂, CO氧化, 程序升温法

Abstract: The catalytic activities of the supported PdO catalysts were found to be dependenton the kind of the support as follows: CeO2>ZrO2>TiO2>Al2O3>SnO2>ZSM-5>SiO2.The reduction state of PdO in the catalyst played an important role in the oxidation activityof the catalyst.PdO/CeO2 was inferior to PdO/Al2O3 in heat-stability, but its activity for COoxidation was higher than PdO/Al2O3, after it had been calcinated at 1200 ℃ for 4h.

Key words: supported PdO catalyst, CO oxidation, temperature programmed method
