Polyacrylonitrile (PAN) nanofibers obtained by electrospinning were used to prepare PAN-based carbon nanofibers (PCNFs) by pre-oxidation, carbonization and high-temperature treatment in NH₃. The PCNFs were used for the removal of low concentrations of NO (5×10⁻⁵) near room temperature (20 °C) by catalytic oxidation. Results indicated that the PCNFs had high porosity and a large specific surface area, and their diameters could be regulated by changing the PAN concentration. The smaller the diameter of the PCNFs the more micropores were developed, and the larger the specific surface area the better the adsorption and catalytic oxidation performance.

碳纳米纤维在室温附近以低浓度催化氧化NO

通过静电纺丝获得的聚丙烯腈（PAN）纳米纤维用于通过在NH _3中进行预氧化，碳化和高温处理来制备PAN基碳纳米纤维（PCNFs）。PCNFs用于通过催化氧化去除室温（20°C）附近的低浓度NO（5×10 ^-5）。结果表明，PCNFs具有较高的孔隙率和较大的比表面积，其直径可以通过改变PAN的浓度来调节。PCNF的直径越小，形成的微孔越多，比表面积越大，吸附和催化氧化性能越好。
