Manganese oxides are among the most promising low-temperature NH3-selective catalytic reduction (NH3-SCR) catalysts. MnO2 with different crystal phases (α-, β-, γ-, and δ-MnO2) exhibits significantly different NH3-SCR performance. The fundamental factors influencing the activity of MnO2 with differe...
