| 摘 要： | 以酚醛树脂低聚物为前驱物, 利用双模板法制备了具有介孔/大孔双孔结构的碳材料. 其中以二氧化硅蛋白石为大孔模板, 以嵌段共聚物自组装结构为介孔模板. 对样品进行了扫描电子显微镜(SEM), 透射电子显微镜(TEM), X射线衍射(XRD)和氮气吸附-脱附实验表征. 结果表明所制备的双孔碳材料大孔直径约为230 nm, 介孔直径10 nm.

| Abstract: | Monolithic carbon sieves with meso-macroporous structure were successfully synthesized with phenol-formaldehyde resin oligomer as precursor by dual-template method. The macropores and mesopores were attained by the removal of SiO_2 opal and self-assembling block copolymer respectively. The as-prepared samples were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and nitrogen adsorption-desorption isotherm measurement. The results indicated that the mesopores with diameters of 10 nm and macropores with diameters of 230 nm were formed during the removal of SiO_2 opal and block copolymer. |
