Binary Mn-FeOx nanoflakes supported on CNT by an one-step redox method for low temperature NO reduction with NH3

Abstract

Binary Mn-FeO _x /CNT-OSR catalysts were prepared by an one-step redox method, and showed 44%–83.7% NO conversion at 80 °C–180 °C. The catalytic activity of the 0.06 Mn-FeO _x /CNT-OSR catalyst is optimum and reaches 65.9%–83.7% at 80 °C–180 °C, resulting from the generation of high valence of MnO _2 and Fe _2 O _3 with weak crystallinity.
