Abstract

A novel core-shell K/Cu/SmCe@TiO₂ catalyst is here reported being highly active on the selective reduction of nitric oxide with carbon monoxide under oxidizing conditions. It was found that the reaction proceeds with the generation of nitrates and nitrites adsorbed on the support and ionic nitrates adsorbed on alkaline sites. Full conversion of CO was achieved from 255 °C and 97% NO conversion was reached at 330 °C.

高活性铜基Ce@TiO2在氧存在下用一氧化碳选择性还原一氧化氮的核壳催化剂

本文报道了一种新型核壳K/Cu/SmCe@TiO2催化剂在氧化条件下对一氧化碳选择性还原一氧化氮具有高活性。结果表明，该反应主要是吸附在载体上的硝酸盐和亚硝酸盐以及吸附在碱性位点上的离子硝酸盐的生成。在255℃时，CO的转化率达到100%，在330℃时，NO的转化率达到97%。
