摘　　要：介绍了微波烧结技术的原理和特点,通过采用微波烧结技术制备了钙钛矿型复合氧化物载体及相应的Pd负载钙钛矿型催化剂。结果表明,相对于常规载体和催化剂的制备方法而言,微波烧结法操作简便、材料损耗少、效率高,可以节约大量的时间和能耗,同时制备的载体和催化剂具有较大的比表面积、较均匀的活性组分分布、相对较高的催化活性。The principle and characteristics of the microwave sintering technology are summarized. The perovskite-type metal oxides supports and the corresponding supported Pd catalyst are prepared by microwave sintering technology. Comparison with the conventional methods, the method of catalysts prepared by the presented technology can shorten the preparation time and save energy. By this way, the prepared catalyst has even activity distribution,bigger specific area and higher activity.
