Dechlorination of chlorobenzene on vanadium-based catalysts for low-temperature SCR
Chlorobenzene (CB) inhibits SCR activity of V-based catalysts at low temperature, though
the adsorption amount is small. NH3 adsorption increases due to the break in the C–Cl bond
during CB oxidation. The dissociated Cl− ions provide extra Brønsted acid sites, leading to
the formation of inactive NH4Cl. Ce and Mn improve dechlorination, forming more NH4Cl on
the catalyst surface.
