摘要：

Highly active Mn-CeOx/CNTs catalysts were first fabricated by a novel redox method, and a formation mechanism was proposed. The asobtained catalyst possessed an amorphous structure, and high Ce3+/(Ce3+ + Ce4+) and O-alpha/(O-alpha + O-beta) ratios, which endowed it with 52.2-98.4% NO conversion at a weight hourly space velocity of 210 000 ml g(cat)(-1) h(-1).
