NOx & VOCs Removal By Nano Mn-Based Catalysts at Low Temperature

Mn-based catalysts showed good activities for NH₃-SCR of NO at low temperatures, and the structure of Nano α-MnO₂ were correlated with the excellent performance of SCR of NOx. Ag atoms in the tunnels of the α-MnO₂ (HMO) exhibited outstanding activation ability to both lattice oxygen and molecule dioxygen at low temperatures.
