The porous Mn2Co1Ox catalysts are prepared by a one-step combustion (CB) method for low temperature deN0x process. This catalyst displays an excellent NH3-SCR activity, achieving 100% NO conversion at 150-300 degrees C. In addition, the catalyst shows high N-2 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 beneficial for the deNO. activity. The catalyst exists abundant Mn4+, Co3+ and surface adsorbed oxygen species, which improve the catalyst's redox ability. Plenty of acid sites from the strong interaction of manganese and cobalt oxide enhance the catalyst performance. (C) 2015 Elsevier B.V. All rights reserved.
