英文摘要	The degradation of volatile organic compounds (VOCs) with simultaneous removal of the secondary pollutant NOx is a promising solution for catalytic elimination of nitrogen-containing VOCs (NVOCs). Herein, a series of mixed CuxMg3-xAlO oxides were prepared and tested for selective catalytic oxidation of n-butylamine. The Cu content of the catalysts significantly impacted their performance. Cu0.4Mg2.6AlO exhibited the best catalytic activity, with 100% conversion of nbutylamine and 83% N-2 selectivity at 350 degrees C. The catalysts were characterized by NH3-TPD, XPS, EPR, UV-vis, and H-2-TPR to reveal the structure-activity relationship. On the basis of DRIFTS results, the reaction mechanism of selective oxidation of nbutylamine was proposed. Additionally, selective catalytic reduction of NO with NH3 was further tested using Cu0.4Mg2.6AlO to remove NOx, which was generated after the selective oxidation process. By coupling selective catalytic oxidation of NVOCs with selective catalytic reduction of NOx, it provides a new effective strategy to synergistically remove NVOCs and NOx.
