T. Tanaka et al., Photoassisted selective catalytic reduction of NO with ammonia in the presence of oxygen at low temperature, PHYS CHEM P, 2(12), 2000, pp. 2681-2682
Rb-ion-modified V2O5/SiO2 (Rb-VS) was found to be an effective catalyst for
photoassisted selective catalytic reduction (SCR) of NO with NH3 in the pr
esence of oxygen at room temperature. V2O5/SiO2 and SiO2 did not promote th
e reaction either in the dark or with irradiation. The reaction mechanism o
ver irradiated Rb-VS is different from the conventional NO SCR with ammonia
. NOx is firstly adsorbed over irradiated Rb-VS in the presence of O-2, fol
lowed by adsorption of NH3.
