| 摘 要： | 以4种比表面积不同的沥青基活性炭纤维为材料，研究了常温下对模拟空气气氛中体积分数为50×10-6的NO的催化氧化性能，并采用氮吸附法、Raman光谱和红外光谱对活性炭纤维进行了表征。结果表明，活性炭纤维可将NO部分催化转化为NO2，较低比表面积的活性炭纤维因为其较窄的孔径分布和较大的类石墨微晶而有利于对NO的催化氧化。

| Abstract: | our pitch-based activated carbon fibers (ACFs) with different specific surface areas were used for catalytic oxidation of NO with a concentration of 50×10-6 at room temperature.ACFs were characterized with nitrogen adsorption, Raman and IR analysis.Results show that some NO can be catalytically oxidized to NO2 by ACFs.Due to its narrow pore size distribution and larger graphite microcrystalline, the ACF with lower specific surface area possesses higher catalytic oxidation ability for NO. |
