摘要

摘要: 以纳米SO₂粒子为模板，酚醛树脂、中间相沥青和聚丙烯腈为炭前躯体制备中孔炭。利用氮气吸附、元素分析和X-射线光电子能谱等分析了不同种类炭前躯体对中孔炭的影响。结果表明：在炭化温度和纳米粒子添加量相同的情况下，不同炭前躯体所制中孔炭的孔结构和表面化学性质不同。中间相沥青基中孔炭中微孔和中孔含量最少，酚醛基中孔炭中含有丰富的微孔和中孔，聚丙烯腈基中孔炭中含有大量的含氮官能团。

Abstract: Mesoporous carbons (MCs) with high-specific surface area and pore volume were synthesized from different carbon precursors (thermosetting phenol resin (TPR), mesophase pitch (MP), and polyacrylonitrile (PAN)) by using nanosize silica particles as a template. The influence of carbon precursors on the properties of as-prepared MCs was investigated by nitrogen adsorption, elemental analysis, and X-ray photoelectron spectroscopy. Results indicated that the pore structure as well as the surface chemical character of the resultant MCs differed greatly despite the preparation conditions being the same. Because the thermal stability of MP was higher and the dispersion ability of silica particles in MP/pyridine solution was poor, MC prepared from MP contained fewer micropores and mesopores compared with that prepared from TPR. In addition, MC derived from PAN had abundant nitrogen functional groups.
