稀土基萤石型氧化物的燃烧特性

The Combustion Property of Rare earth based Fluorite Type Oxide

Ｃｅ基萤石型材料因低价阳离子Ｌｎ３＋的掺杂，降低了它的还原温度，增强了氧化还原能力，故可较好地促进甲烷等挥发性有机物的完全燃烧，具有与钙钛矿形型化合物相类似的性能，而其热稳定性更好，因而有望在醇类代用燃料汽车的尾气净化处理中发挥更大作用。

Doping with lower valence cations,the reducing temperature of Ce based fluorite type materials can be lowered,and the reduction oxidation property can be enhanced. This facilitates the combustion of methane as perovskite compounds do,and the former has a better thermal stability. This material can play an important role in the treatment of exhaust gas from alcohol fueled vehicles.
