| 摘 要： | 采用硬模板法，以间位碳硼烷为硼源、3-氨基苯基乙炔树脂为氮源和碳源、介孔二氧化硅（SBA-15）为硬模板，成功制备了氮硼共掺杂的有序介孔碳材料（NBC）。采用X射线衍射（XRD）、N2吸附-脱附测试、透射电镜（TEM）和X射线光电子能谱（XPS）研究了前驱体中B与N的物质的量之比（nB/nN）对NBC结构的影响。采用紫外-可见分光光度计（UV-Vis）研究了NBC对甲基橙染料的吸附性能。结果表明：NBC具有二维六方的有序结构，孔径可调且分布集中在3~6 nm。其中，NBC-1.0样品（nB/nN=1.0）具有最高的比表面积（1 560 m2/g）、最大比孔容（1.92 cm3/g）及高度有序性。相比于传统的活性炭吸附剂（吸附量61 mg/g），NBC-1.0可以实现对甲基橙染料的快速、有效吸附，其吸附量可达214 mg/g。

| Abstract: | Utilizing novel m-carborane and 3-ethynylbenzenamine resin as precursor, ordered mesoporous carbon co-doped with nitrogen and boron NBC was successfully prepared by hard-template route. Methyl orange anionic dye was selected to investigate the adsorption behavior on NBC. The adsorption capacity of methyl orange dye on NBC and activated carbon (Ac) was studied using UV-Vis spectrophotometer. The effects of precursors molar ratio of B to N (nB/nN) on the texture and heteroatoms content of NBC were investigated. X-ray diffraction (XRD), N2 adsorption and desorption and transmission electron microscopy (TEM) were used to characterize the morphology of prepared NBC samples. X-ray photoelectron spectroscopy (XPS) was used to investigate atomic percentage and bonding structure. Results showed that NBC had a two-dimensional hexagonal ordered structure with a pore size distribution centered at 3-6 nm. The increasing nB/nN (from 0.5 to 1.0) appropriately enhanced the pore size. However, when nB/nN increased from 1.0 to 2.0, NBC specific surface area and pore size gradually decreased and ordered structure was partially destroyed. When nB/nN was 1.0, NBC exhibited the highest specific surface area (1 560 m2/g) and the largest specific pore volume (1.92 cm3/g). Besides, the atomic percentage of boron and nitrogen could be adjusted to 4.95% and 6.32%, respectively. Compared to the conventional activated carbon adsorbent (61 mg/g), NBC-1.0 (nB/nN=1) exhibited rapid and effective adsorption performance (214 mg/g), which showed great potential as efficient adsorbent for removal of methyl orange dye. |
