以低分子量硼掺杂酚醛树脂(BPF)为炭前驱体、正硅酸四乙酯(TEOS)为无机前驱体、嵌段共聚物F127(PEO_(106)PPO_(70)PEO_(106))为软模板,采用溶剂挥发诱导自组装法(EISA)合成具有高比表面积、高硼含量的硼掺杂有序介孔炭(BOMC)。利用傅里叶变换红外光谱仪、X射线光电子能谱仪、X射线衍射仪、氮气吸-脱附仪、透射电子显微镜对硼掺杂有序介孔炭的组成、结构及形貌等进行表征。结果表明,制得的硼掺杂有序介孔炭材料具有高度有序的二维六方介观结构,其比表面积和硼含量分别高达891.17 m2/g和1.36%,孔径为5.5 nm。
The low molecular weight boron-doped phenolic resin (BPF) was used as carbon precursor and tetraethyl orthosilicate (TEOS) as inorganic precursor. The block copolymer F127 (PEO 106 PPO 70 PEO 106) Soft template, boron-doped ordered mesoporous carbon (BOMC) with high specific surface area and high boron content was synthesized by solvent evaporation induced self-assembly (EISA). The composition, structure and morphology of boron-doped ordered mesoporous carbon were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nitrogen adsorption-desorption spectroscopy and transmission electron microscopy. The results show that the prepared ordered boron-doped ordered mesoporous carbon material has a highly ordered two-dimensional hexagonal mesoscopic structure with a specific surface area and boron content of 891.17 m2 / g and 1.36%, respectively, and a pore diameter of 5.5 nm.
