摘要:
In some embodiments, the present disclosure pertains to methods of making graphene quantum dots from a carbon source (e.g., coal, coke, and combinations thereof) by exposing the carbon source to an oxidant. In some embodiments, the methods of the present disclosure further comprise a step of separating the formed graphene quantum dots from the oxidant. In some embodiments, the methods of the present disclosure further comprise a step of reducing the formed graphene quantum dots. In some embodiments, the methods of the present disclosure further comprise a step of enhancing a quantum yield of the graphene quantum dots. In further embodiments, the methods of the present disclosure also include a step of controlling the diameter of the formed graphene quantum dots by selecting the carbon source. In some embodiments, the formed graphene quantum dots comprise oxygen addends or amorphous carbon addends on their edges.
摘要(中):
在一些实施方案中,本公开涉及通过将碳源暴露于氧化剂从碳源(例如,煤,焦炭及其组合)制备石墨烯量子点的方法。 在一些实施方案中,本公开的方法进一步包括从形成的石墨烯量子点与氧化剂分离的步骤。 在一些实施方案中,本公开的方法还包括减少形成的石墨烯量子点的步骤。 在一些实施方案中,本发明的方法还包括提高石墨烯量子点的量子产率的步骤。 在另外的实施方案中,本公开的方法还包括通过选择碳源来控制形成的石墨烯量子点的直径的步骤。 在一些实施方案中,形成的石墨烯量子点在其边缘上包括氧加成物或无定形碳添加物。
