Abstract

The performance of Mn/Beta in ozone catalytic oxidation (OZCO) of n-butane was optimized by variation of the Mn content (0.6–10 wt%) and localization of Mn species in the zeolite structure (as Mn2+ ions in the cationic position or MnOx species). It was found that localization of Mn2+ ions in the cationic positions of the zeolite favors high efficiency of ozone utilization in the OZCO process by minimizing O3 consumption, while the formation of Mn oxide species improves the catalyst activity at a low temperature (50–70 °C), though at the expense of the ozone utilization efficiency.

通过改变Mn含量及其在沸石结构中的定位来调整Mn/Beta在臭氧催化氧化VOCs中的性能
Mn/Beta在正丁烷臭氧催化氧化(OZCO)中的性能通过改变Mn含量(0.6-10 wt%)和Mn在沸石结构中的定位(作为阳离子位置的Mn2+离子或MnOx种)来优化。研究发现,在沸石的阳离子位置上定位Mn2+离子有利于OZCO过程中臭氧的高效利用,减少了O3的消耗,而Mn氧化物的形成在低温(50-70℃)下提高了催化剂的活性,但以牺牲臭氧的利用效率为代价。

期刊介绍: Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
