Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...
