“…Carbon is a special catalyst support material with relatively inert property, so that undesired side reactions catalyzed by the support surface hardly occur. Various carbon materials supported vanadium-free catalysts, including CeO2/ACF(activated carbon fiber), 78,79 Fe2O3, Co2O3 or Mn2O3/ACF, 80 MnOx/CNT (carbon nanotube), [81][82][83] CuO/CNT, 84 MnOx-CeO2/CNT, [85][86][87][88] Fe2O3, Cr2O3 or CuO/AC (active carbons), 89,90 Cu or Mn/active carbon honeycomb, 91 and MnOx-CeO2/ active carbon honeycomb, 34 have been studied for lowtemperature SCR reaction. These catalysts exhibited relatively high SCR activities at low temperatures, but the inadequate SO2 tolerance is a fatal problem for their industrial application.…”

ARTICLE This journal isSelective catalytic reduction of NOx with NH3 (NH3-SCR) at low temperature is a major challenge in environmental catalysis. In recent years, great efforts have been applied to the development of low-temperature SCR catalysts for both stationary sources and diesel engines. Mn-based catalysts have attracted great attentions due to their excellent low-temperature activity. However, vulnerability to SO2 and H2O poisoning and preference for N2O formation make these catalysts still far away from industrial application. V2O5 loaded on carbon materials have shown both high SCR activity and SO2 tolerance at low-temperature. This type of catalyst is very promising for the applications in low-temperature SCR for stationary sources. Recently, Cu containing small pore zeolites, such as Cu-SSZ-13 and Cu-SAPO-34 with CHA structure and Cu-SSZ-39 and Cu-SAPO-18 with AEI structure, were shown to have very high activity at low temperature and excellent hydrothermal stability at high temperature and thus received much attention for the applications on diesel vehicles. In this review, we will focus on the recent studies of low-temperature NH3-SCR catalysts. In addition, the future directions of low-temperature SCR development will also be discussed.

“…It was found that the best additives were Cu, V and Fe, mainly in their binary mixtures, for which a synergetic effect was evidenced. In particular, copper has been reported to be a good catalyst for the adsorption of SO 2 at low temperatures, and very low adsorption capacities have been reported in the absence of copper. − Tseng et al found that the catalytic reaction between SO 2 and supported copper species was affected by the surface functional groups that are generated during the synthesis of metal-loaded activated carbon supports.…”

Low Temperature Catalytic Adsorption of SO₂ on Activated Carbon

et al. 2008

Catalytic adsorption of SO 2 on activated carbon materials provides an appropriate alternative for the control of low concentration emissions of this air pollutant. The surface complexes formed upon SO 2 adsorption at 30 °C were studied by X-ray photoelectron spectroscopy (XPS) and temperature-programmed desorption (TPD). The effect of the addition of O 2 and the presence of copper as catalyst were studied. Copper assisted the oxygen transfer to the carbon matrix. For the Cu-impregnated carbon sample, the presence of O 2 favored SO 2 adsorption by increasing the breakthrough time, the adsorption capacity and the formation of sulfur and oxygen complexes of higher thermal stabilities, which mainly desorb as SO 2 and CO 2 .
