Abstract

A large amount of polymeric vanadyl species owing to higher interaction energy between vanadia and anatase than rutile and the synergistic effect of vanadium oxides, anatase and rutile TiO₂ contributes to an excellent NH₃-SCR activity of the vanadia-based catalysts with high rutile content and low specific surface area.
