Abstract
In this work, titanate nanotubes (TNT) with different pore structure were synthesized through hydrothermal method by using various TiO2 particles as starting materials. V2O5 and WO3 was deposited on the as-synthesized TNT structure by wet impregnation. In the selective catalytic reduction of NO with NH3, it was found that the catalytic activity of V2O5-WO3/TNT catalysts was unaffected by the initial different pore structure because the pore structure collapsed during the active metal impregnation and subsequent calcination. Also, kinetic analysis showed that the apparent activation energies of V2O5-WO3/TNT catalysts and traditional V2O5-WO3/TiO2 catalyst were the similar values, which indicate that the nature of active sites in the SCR reaction on both catalysts would not be significantly different.
