| 摘 要： | 采用水热法制备了超轻氮掺杂石墨烯气凝胶。分析表征结果表明，多巴胺不仅为还原剂而且提供氮源，石墨烯溶液前躯体的pH值对水热法制备超轻氮掺杂石墨烯气凝胶很大的影响，通过调节多巴胺和L-精氨酸在石墨烯溶液前躯体的浓度，可制备密度为2.54 mg/cm3超轻氮掺杂石墨烯气凝胶，由于氮掺杂、低密度和大的比表面积，超轻氮掺杂石墨烯气凝胶对各种油品都有良好的吸附性能。

| Abstract: | Ultralight and nitrogen doped graphene aerogels (UNGAS) are developed by a hydrothermal method in the presence of graphene, dopamine (DA) and L-arginine. Analysis shows that DA can functionalize the graphene surface and also embed nitrogen atoms onto the graphene sheets upon pyrolysis, and the values of pH on the hydrothermal fabrication of UNGAS have great influence on the formation of UNGAS. By adjusting the amount of L-arginine and dopamine in the precursor mixture, UNGAS with a density as low as 2.54 mg/cm3 can be prepared. The UNGAS show high absorption capacity for various oils due to low density, N doping and large surface area. |
