Herein, we demonstrate large surface area and ultrahigh porosity of three-dimensional ultralight, macro- and micro-porous reduced graphene oxide (m2-rGO) monoliths by simple and clean activation chemistry. The resultant actived m2-rGO adsorbents are applied into supercapacitor to demonstrate the superiority of hierarchical textures and structures. The activated 3D m2-rGO monoliths are attractive as high capacitive materials because of facile accessibility to adsorption site and fast mass transport. Furthermore, the macroscopically monolithic adsorbents assembled by nanoscopic graphene multilayers can expand their applicative fields because handling them is easier than doing powdery sorbents and monoliths are chemically and structurally uniform and thus, more fitted to process applications. |
