Significant promotion effect of the rutile phase on V2O5/TiO2 catalysts for NH3-SCR

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.

Automated summary

The excellent NH3-SCR activity of vanadia-based catalysts with high rutile content and low specific surface area is attributed to the higher interaction energy between vanadia and anatase than rutile, as well as the synergistic effect of vanadium oxides, anatase, and rutile TiO2.
