The effects of H2O on a vanadium-based catalyst for NH3-SCR at low temperatures: a quantitative study of the reaction pathway and active sites

The effects of H₂O on the adsorption amounts of NO, NO₂, and NH₃, NH₃-SCR reaction pathway and active site distribution over V₂O₅/WO₃–TiO₂ at low temperatures were quantitatively studied by the TRM and TPSR.
