Role of WO 3 in NO Reduction with NH 3 over V 2 O 5 -WO 3 /TiO 2 : A New Insight from the Kinetic Study

WO 3 role in NO reduction over V 2 O 5 -WO 3 /TiO 2 was studied by comparing the kinetic parameters of the selective catalytic reduction (SCR) reaction, the non selective catalytic reduction (NSCR) reaction and the C–O reaction. The results show that the SCR reaction over V 2 O 5 /TiO 2 was promoted after WO 3 incorporation, while the NSCR reaction and the C–O reaction were both restrained. Graphical Abstract
