title: Effect of TiO2 surface properties on the SCR activity of NOx emission abatement catalyst.
abstract: NOx emission abatement catalysts V2O5 supported on various TiO2 including anatase, rutile and mixture of both were investigated with various physico-chemical measurements such as BET, NH3-TPD, NARP, XRD and so on, and the effect of TiO2 surface properties on the SCR (selective catalytic reduction) activity of V2O5/TiO2 catalysts was studied. It was found that the TiO2 surface properties had strong effect on the SCR activity of V2O5/TiO2 catalysts. The stronger acidic property resulted in the higher exposure of active sites as well as the higher SCR activity.
