Catalytic performance of highly dispersed WO3 loaded on CeO2 in the selective catalytic reduction of NO by NH3

WO3 dispersed on the CeO2 surface inhibits adsorption of NOx species and promotes NH3 adsorption on supported WO3/CeO2 catalysts, which promotes the NH3 selective catalytic reduction reaction via the Eley-Rideal (E-R) route.
