摘    要:以自制PAN-基聚丙烯腈活性碳纤维ACF-PAN(ACF-活性碳纤维、PAN-聚丙烯腈)和改性处理的ACF-PAN吸附SO_2,借助IR、x-光电子能谱分析等研究ACF-PAN改性处理及吸附SO_2前后表面结构变化。结果表明:各型ACF-PAN吸附SO_2的活性中心为表面结构中的含氮官能团以及引入的金属氧化物,其吸附机理是活性氮催化或电子传递。

关 键 词:活性碳纤维  改性  表面结构  吸附SO_2机理

Abstract:The mechanism of ACF-PAN and modified ACFPAN adsorbing SO2 and its activated center are studied in this paper, as well as the change of surface structure before and after SO2 adsorption, by IP and X-ray photoelectron spetrometry.The results indicate that the activated center on modified ACFPAN and ACF-PAN prepared consists of functional group containing nitrogen and metal oxide. The adsorption mechanism of SO2 on ACF-PAN and modified ACF-PAN is the catalysis by activated nitrogen or electron transport.
Keywords:Active carbon fiberi Modify  Surface structure  Mechanism ofSO_2 adsorption
