氧化铈具有萤石矿型结构，并且随着氧化还原气氛的不同，铈可以Ｃｅ４＋／Ｃｅ３＋价态存在，在结构中易于形成流动性的氧空位，这些性质使得它成为很好的催化氧化活性材料；ＣｅＯ２经贱金属掺杂之后，可进一步提高其催化氧化活性，近年来倍受人们的重视［１，２］．锰的... Cerium oxide has a fluorite mineral structure, and with the redox atmosphere, cerium can exist in the Ce4 + / Ce3 + valence state and easily form a fluid oxygen vacancy in the structure, which makes it a very good catalyst for the catalytic oxidation of active materials ; CeO2 after base metal doping can further enhance its catalytic oxidation activity, in recent years much attention [1,2].
