摘要：

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 degrees C at a high space velocity of 32,000 h(-1). (C) 2014 Elsevier B.V. All rights reserved.
