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

Abstract Binary Mn-FeOx/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-FeOx/CNT-OSR catalyst is optimum and reaches 65.9%–83.7% at 80 °C–180 °C, resulting from the generation of high valence of MnO2 and Fe2O3 with weak crystallinity.
