酚醛树脂基中空碳微球的制备及其孔结构研究 Fabrication of Phenolic Formaldehyde-Basedhollow Carbon Microspheres and Study of Their Pore Structure

本文利用磺化聚苯乙烯微球作为模板，酚醛树脂作为碳前驱体制备出直径约460 nm，壁厚约80 nm的中空碳微球。利用氮气吸附法对所制备的中空碳微球进行孔结构表征，结果显示其比表面积为492.89 m2/g，孔结构以直径为4 nm左右的中孔为主。 In this study, hollow carbon microspheres with diameter about 460 nm and a shell of about 80 nm were fab- ricated using sulfonated polystyrene microspheres as templates and phenolic formaldehyde resins as carbon precursor. The pore structure of hollow carbon microspheres was characterized through nitrogen adsorption method, which showed that the specific area of hollow carbon microspheres was 492.89 m2/g and the pores were mainly composed of mesopores with diameter about 4 nm.
