氮掺杂已经成为改变从活性炭到石墨烯的碳材料性质的有力方式。在这里，我们报告了一种溶液化学方法，氮掺杂的胶体石墨烯量子点具有明确的结构。N-掺杂被证明显着影响量子点的性质，包括出现的尺寸依赖的氧还原反应的电催化活性。
Nitrogen doping has been a powerful way to modify the properties of carbon materials ranging from activated carbon to graphene. Here we report on a solution chemistry approach to nitrogen-doped colloidal graphene quantum dots with well-defined structures. N-doping was demonstrated to significantly affect the properties of the quantum dots, including the emergence of size-dependent electrocatalytic activity for the oxygen reduction reaction.
