Facile modifications of HKUST-1 by V, Nb and Mn for low-temperature selective catalytic reduction of nitrogen oxides by NH3
نویسندگان
چکیده
HKUST-1 catalysts were impregnated with vanadium, niobium and manganese species tested in NH3-SCR for NO removal. No reduction of by NH3 was registered the unmodified disappearance attributed to adsorption. After a pre-treatment at 185 °C, best catalytic performance found HKUST-1-Mn 100% 80% conversion NO, respectively °C. For first time, H2O tolerance examined on commercial promoted Mn. The addition water vapor resulted decrease conversions, which immediately recovered when feeding stopped. dropped from 74% 68% after 35 min addition.

The catalysts of iron-doped Mn-Ce/TiO2 (Fe-Mn-Ce/TiO2) prepared by sol-gel method were investigated for low temperature selective catalytic reduction (SCR) of NO with NH3. It was found that the NO conversion over Fe-Mn-Ce/TiO2 was obviously improved after iron doping compared with that over Mn-Ce/TiO2. Fe-Mn-Ce/TiO2 with the molar ratio of Fe/Ti = 0.1 exhibited the highest activity. The results...
