P. Ciambelli et al., THE INFLUENCE OF SULFATE ON THE CATALYTIC PROPERTIES OF V2O5-TIO2 ANDWO3-TIO2 IN THE REDUCTION OF NITRIC-OXIDE WITH AMMONIA, Catalysis today, 29(1-4), 1996, pp. 161-164
The effect of sulphate on the catalytic properties of V2O5/TiO2 and WO
3/TiO2 in the selective reduction of NO with NH3 has been investigated
. For both catalytic systems, the presence of sulphate results in the
enhancement of catalytic activity without reduction of selectivity to
nitrogen. The rate of NO reduction depends on the sulphate content, wh
ich is affected by the original composition of titania, the method of
catalyst preparation and the metal oxide loading.
