钙钛矿型复合氧化物催化分解NO_x的研究

Study on Perovskite Mixed Metal Oxides for NO_x Decomposition

氮氧化物(NOx)是严重的大气污染物,对环境和人类都会造成极大的伤害。钙钛矿型复合氧化物由于其结构稳定,其晶格内部可容纳大量不同的金属元素,表现出独特的催化消除NOx的性能。对钙钛矿型复合氧化物的结构、催化分解NOx的机理进行了综述。

Nitrogen oxides （NOx） are serious pollutants in earth＇s atmosphere, they are harmful gases both to environment and human body. As one catalyst for NOx removal, special attention has been paid to the use of perovskite mixed oxides due to their remarkable stability, and perovskite-type oxides can accommodate a large number of metal, which result in the obtained samples possessing special character. Summerazed the structure of perovskite mixed oxides and its catalysis for NOx decomposition.
