Porous N-doped carbon material (NCM) derived from deep eutectic solvent (DES) is successfully prepared. The preparation of NCM depends mainly on heating treatment and does not demand activation and filtration. The heating process contains three steps: (1) forming a DES that consists of glucose and urea at 100 °C; (2) preparing dried precursors by microwave; (3) and carbonizing the precursor. After heating, the resulting NCM can be obtained. The as-prepared NCM exhibits high specific surface area, rich micropores and strong Lewis basicity. Accordingly, NCMs show good adsorption performance for 4-nitrophenol or methylene blue in aqueous solution and thiophenic sulfurs in the oil phase. Apparently, NCM derived from DES not only possesses a simple preparation process, but also can remove a wide spectrum of organic pollutants. Therefore, the NCM prepared here may be promising for practical application.
成功制备了一种由低共熔溶剂（DES）衍生的多孔氮掺杂碳材料（NCM）。NCM的制备主要依赖于热处理，无需活化和过滤。加热过程包括三个步骤：（1）在100℃下形成由葡萄糖和尿素组成的DES；（2）通过微波制备干燥的前驱体；（3）将前驱体碳化。加热后，即可得到所得的NCM。所制备的NCM具有高比表面积、丰富的微孔和较强的路易斯碱性。因此，NCM对水溶液中的4-硝基苯酚或亚甲基蓝以及油相中的噻吩类硫化物表现出良好的吸附性能。显然，由DES衍生的NCM不仅制备过程简单，而且能够去除多种有机污染物。因此，这里制备的NCM在实际应用中可能具有广阔前景。
