Fabrication of mesoporous graphene electrodes with enhanced capacitive deionization

Mesoporous graphene electrodes are facilely fabricated via a simple thermal treatment of graphene oxide as well as site-localized etching of Fe3O4 nanoparticles (E-Gr-Fe3O4). Influences of FeCl2 precursor on the amount of Fe3O4 nanoparticles and textural properties of E-Gr-Fe3O4 are investigated. The obtained graphene framework exhibits a porous structure with a specific surface area of 362 m2/g and excellent specific capacity of 128 F/g, which...
