摘要
本文从原子结构分析了变价稀土元素原子的结构特点 ,从机理上分析了变价稀土氧化物对催化剂原子氧化价的稳定性、贮氧能力和热稳定性等性能增强的根源 ,从理论上深入认识了稀土氧化物的助催化作用。
In this work,atom structure features of rare earth elements have been analyzed.Reasons why changeable valence rare earth oxide can strengthen stability of atom valence in oxidized state,ability to conserve oxygen and heat stability for catalysts are discussed from mechanism.Auxiliary catalyst functions are understood more deeply on the base theory.
