Abstract

A novel type of multifunctional three-dimensional (3D) microchannel-network graphene foams (μCNGFs) has been facilely fabricated by using an alumina fiber blanket (AFB) template. The μCNGF with reticular space structures showed an excellent electrochemical property for electrochemical double-layer capacitors with a specific capacitance of as high as 216 F g^-1 at a current density of 0.5 A g^-1 in a two-electrode system. Adsorption tests of various liquids further proved the outstanding adsorbing features of the μCNGF such as fast and efficient adsorption of liquids and repeatable recyclability for petrol. Results indicated that the μCNGF has unique advantages as a novel type of electrode material for high-performance supercapacitors and is well qualified as an efficient and versatile absorber of hazardous organic liquids with potential applications in diverse industrial and environmental areas.
