NH3 selective catalytic reduction (NH3-SCR) is the most prevalent and effective method for removing nitrogen oxides. Over past few decades, manganese (Mn)-based catalysts have demonstrated strong activity been extensively studied low-temperature NH3-SCR reactions. This paper provides an in-depth introduction to four forms of Mn-based catalysts: single oxide-based catalysts, binary metal oxide ternary multivariate nano-Mn-based catalysts. Advances made in enhancing catalysts’ redox performance acidity, increasing active component’s dispersion, lowering binding energy, enlarging specific surface area, raising Mn4+/Mn3+ ratio, enriching adsorbed oxygen by optimizing preparation methods, altering oxidation state components, modifying crystal phases, adjusting morphology along with various modifications. The mechanism reactions has elucidated using characterization techniques. Finally, research directions future prospects are discussed, aiming accelerate commercial application new
