Insight into N2O Formation Over Different Crystal Phases of MnO2 During Low-Temperature NH3–SCR of NO
Different crystal phases of MnO 2 were synthesized and tested for NH 3 –SCR of NO and NH 3 oxidation performances during 50–120 °C. Among those catalysts, α-MnO 2 showed the most superior SCR performance for NO x conversion and N 2 selectivity, and NH 3 species on its surface were active to react wi...
