摘　　要：机动车尾气净化控制的一个难点在于冷启动阶段,此时由于温度较低,催化剂尚未完全起作用,导致排出的污染物浓度较高。阐述了活性炭纤维的基本特性,特别是其低温吸附与催化性能对NO和CO的转化作用,讨论了活性炭纤维作为机动车尾气净化材料所需的改性及方法,并展望了其应用前景。One of the difficulties in purification of vehicle exhaust occurs at the stage of cold boot when the exhaust temperature is too low and the catalyst does not work efficiently, leading to a relatively high concentration of pollutants. The characteristics of activated carbon fibre, especially the effect of the adsorption at low temperature and catalytic performance on the conversion of NO and CO, are presented. The modification of activated carbon fibre to be used as purifying materials for vehicle exhaust is discussed and the potential application is prospected.
