| 摘 要： | 以HY分子筛为模板, 采用糠醇浸渍炭化法和糠醇浸渍-乙腈气相沉积炭化法制备了多种微孔炭材料, 分别标记为PFA系列和AN系列, 并研究了其电化学电容性能. X射线衍射(XRD)测试表明AN系列炭材料较好地复制了HY分子筛模板的孔结构有序性. X射线光电子能谱仪(XPS)测试表明, 乙腈气相沉积在炭材料中引入丰富的含氮官能团. 氮气吸附测试表明, 炭材料是典型的微孔材料, 具有较高的比表面积, 较窄的孔径分布范围. 电化学测试表明, AN系列炭材料电容性能较好, 并具有明显的赝电容, 其中AN8的比电容最大可达210 F·g-1. AN系列炭材料的电容保持率与材料的导电性和介孔率有关.

| Abstract: | Several microporous carbons were prepared by polyfurfuryl alcohol-impregnation and impregnation-acetonitrile chemical vapor deposition (CVD) using zeolite HY as a template,denoted as PFA carbons and AN carbons,respectively.These were used as electrode materials for supercapacitors.X-ray diffraction (XRD) patterns show that the structural regularity of the zeolite was well-replicated by the carbon structures prepared by impregnation-CVD.X-ray photoelectron spectroscopy (XPS) confirmed that the AN carbons pos... |
