An investigation on the redox kinetics of NH3-SCR over a V/Mo/Ti catalyst: Evidence of a direct role of NO in the re-oxidation step

摘要

This study addresses a kinetic investigation of NH3-SCR on commercial SCR catalysts with composition V2O5/MoO3/TiO2. Objective of the study is an improved kinetic description of the reaction, based on the recognition of the redox nature of the V-site; which calls for an understanding of the effect of O-2.
