Low-temperature NO reduction with NH3 over Mn–CeOx/CNT catalysts prepared by a liquid-phase method

Abstract

Herein, we report a simple and effective way to prepare Mn–Ce mixed-oxide catalysts supported on carbon nanotubes for low-temperature selective catalytic reduction of NO with NH₃. The catalysts with amorphous structures all showed nearly 100% NO conversion at 120–180 °C with a space velocity of 30 000 h⁻¹.
