石墨烯寿命：通过制备超轻、氮掺杂的3D石墨烯框架，实现了（2.1±0.3）mg cm−3的密度，这是迄今为止石墨烯框架结构的最低密度（见蒲公英上平衡的材料块照片）。它对油和有机溶剂的吸附能力远高于最佳的碳质吸附剂，是一种很有前途的超级电容器电极材料（484 F g−1）和氧还原反应的无金属催化剂。
Graphene lite: A density of (2.1±0.3) mg cm− 3, the lowest to date for a graphene framework architecture, is achieved by preparing an ultralight, N‐doped, 3D graphene framework (see photo of a block of the material balancing on a dandelion). Its adsorption capacity for oils and organic solvents is much higher than that of the best carbonaceous sorbents, and it is a promising electrode material for supercapacitors (484 F g− 1) and as a metal‐free catalyst for the oxygen reduction reaction.
