Preparation of Mn–FeOx/CNTs catalysts by redox co-precipitation and application in low-temperature NO reduction with NH3

• Mn–FeOx/CNTs catalysts were firstly prepared by redox co-precipitation method.
• 12% Mn–FeOx/CNTs catalysts exhibited first-rate SCR activity at 80–180 °C.
• The as-obtained catalysts were possessed of amorphous structure.

A novel redox co-precipitation method was firstly adopted to prepare the Mn–FeOx/CNTs catalysts for use in low-temperature NO reduction with NH3. The catalysts were possessed of amorphous structure and exhibited 80–100% NO conversion at 140–180 °C at a high space velocity of 32,000 h− 1.
