| 摘 要： | 采用不同修饰工艺对微纳米多孔碳质材料进行处理,考察了修饰前后材料表面官能团的变化及其对苯酚吸附能力的影响,并结合Boehm滴定、Fourier变换红外光谱仪和X射线光电子能谱对材料表面官能团进行表征。结果表明：经高温（800℃）和尿素修饰后,材料的比表面积分别下降了41.9%和19.6%,苯酚吸附性能分别提升了21.2%和37%;经硝酸预改性的样品表面存在大量的羧基和酚羟基酸性基团,尿素改性时更利于吡啶和吡咯结构的生成。 |

| Abstract: | A micro-nano porous carbon material (MNC) was modified by different methods. The effect of surface functional groups on the phenol adsorption capacity was investigated by the Boehm titration, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy, respectively. The results show that after heat treatment at a high temperature (800 ℃) and urea modification, the specific surface areas of the MNC are decreased by 41.9% and 19.6%, respectively, and the phenol adsorption capacities are increased by 21.2% and 37%, respectively. For the modification by nitric acid followed by urea, the presence of acidic groups (particularly for carboxyl and phenolic hydroxyl groups) improved the surface defects of graphite microcrystalline, which could favor the implant of nitrogen-containing functional groups, especially for the generation of pyridine and pyrrole. |
