Title
One-step synthesis of ternary MnO2–Fe2O3–CeO2–Ce2O3/CNT catalysts for use in low-temperature NO reduction with NH3
Abstract

•Ternary MnO2–Fe2O3–CeO2–Ce2O3/CNT catalysts were synthesized by one-step method.•Ternary MnO2–Fe2O3–CeO2–Ce2O3/CNT showed 73.6–99.4% NO conversion at 120–180 °C.•The as-prepared catalysts mainly consisted of amorphous MnO2, Fe2O3, Ce2O3 and CeO2.

In this article, a facile one-step strategy for the synthesis of ternary MnO2–Fe2O3–CeO2–Ce2O3/carbon nanotubes (CNT) catalysts was discussed. The as-prepared catalysts exhibited 73.6–99.4% NO conversion at 120–180 °C at a weight hourly space velocity (WHSV) of 210 000 ml·gcat− 1·h− 1, which benefited from the formation of amorphous MnO2, Fe2O3, CeO2, and Ce2O3, as well as high Ce3 + and surface oxygen (Oε) contents. The mechanism of formation of MnO2–Fe2O3–CeO2–Ce2O3/CNT catalysts was also proposed.
