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.
