摘　　要：综述了近年来国内外稀土钙钛矿型复合氧化物的研究进展,阐述了由于ABO3稀土钙钛矿型催化剂A、B位的取代,出现了许多钙钛矿型及类似钙钛矿型晶体结构,增加了氧格空位,提高了钙钛矿型催化剂的催化活性。并且详细介绍了催化剂及其载体的制备方法及工艺。The paper summarizes the up - to - date research advancement of rare earth perovskite - type compound oxides at home and abroad, expounds that the A - site and B - site substituted by foreign ions result in the different crystal structures of - type oxides and perovskite - like oxides formed, oxygen lattices increased and their catalytic activity improved. And the preparation methods of the catalysts and supports are presented.
