New SCR Catalysts Based on Mn Supported on Simple or Mixed Aerogel Oxides: Effect of Sulfates Addition

New SCR catalysts based on Mn supported on simple or mixed aerogel oxides (Mn/ZrO2, Mn/CeO2-ZrO2 and Mn/CeO2-ZrO2-SO42−) were prepared for selective catalytic reduction of nitrogen oxide by ammonia (NO-SCR by NH3). One step sol gel method followed by supercritical drying process were used for elabor...
