Abstract
With graphene oxide (GO) as ‘shape-directing’ agent, carbon aerogels with tunable hierarchical porous structure were prepared by one-step carbonization method. It was found that the content of GO had a significant effect on their pore structures. When GO loading was up to 1.43 wt‱, it possessed an ultrahigh specific surface area (SSA) of 2728 m2 g−1, large pore volume of 1.82 cm3 g−1 and excellent mechanical properties. Benefiting from the high SSA and unique hierarchical porous microstructure, possible future applications of the as-obtained carbon aerogels could be in the fields of energy storage, electrochemistry, and adsorption.
