Abstract
The porousMn2Co1Ox catalysts are prepared by a one-step combustion (CB) method for lowtemperature deNOx process. This catalyst displays an excellentNH3-SCR activity, achieving 100%NOx conversion at 150-300 °C. In addition, the catalyst shows high N2 selectivity, wide operating temperature window, high stability, and high H2O and SO2 resistance. The crystalline phase of CoMn2O4, porous structure and large specific surface areaare benefi- cial for the deNOx activity. The catalyst exists abundant Mn4+, Co3+ and surface adsorbed oxygen species, which improve the catalyst's redox ability. Plenty of acid sites fromthe strong interaction ofmanganese and cobalt oxide enhance the catalyst performance.
