Abstract

A subtle catalyst design is provided with stably incorporated binary catalytically active centers of CuO and MnO₂ on the surface wall of mesoporous TiO₂. Such unique features render these mesoporous composites highly promising in the low-temperature selective catalytic reduction of NO with NH₃, including high NO conversion efficiency, and superior H₂O and SO₂ resistance.
