Novel Pd-Au/TiO2 catalyst for the selective catalytic reduction of NOx by H-2

Abstract

Novel Pd-Au/TiO2 catalyst exhibited high catalytic activity with a wide temperature window for the selective catalytic reduction of NOx by H-2 in the presence of oxygen. The synergetic effect between Pd and Au contributes to the formation of Pd-0 and Pd-Au alloy, thus promoting the NOx reduction to proceed.
