Design of graphene-coated hollow mesoporous carbon spheres as high performance electrodes for capacitive deionization

Abstract

Graphene-coated hollow mesoporous carbon spheres are rationally designed and originally used as efficient electrode materials for capacitive deionization.

Activated carbon electrodes: Electrochemical oxidation coupled with desalination for wastewater treatment

“…The ions are electrosorbed by applied a potential to the porous electrodes and desorbed by shorting the electrodes or reversing the potential. The most frequently used electrodes are porous carbon materials with high surface areas, abundant pore structures and some surface groups Gao et al, 2013Gao et al, , 2014Wang et al, 2014).…”

Thermo-stabilized, porous polyimide microspheres prepared from nanosized SiO2 templating via in situ polymerization

“…In the last decades, owing to several special addedvalue applications in the area of catalysts, separation, chromatographic carriers, adsorbents, lowdielectric fillers, storage and deliver carriers for drugs, phonics crystals, nanoelectronics, or biotechnology [1][2][3][4], porous polymer materials, especially spherical ones, have been the hotspot of active study area in the development of new materials and some of them have been shown to be of practical use. Herein, an excellent porous polymer matrix should satisfy a variety of requirements, such as desirable thermal stability, chemical resistance and high modulus to support the void structure.…”

Highly porous activated carbons from resource-recovered Leucaena leucocephala wood as capacitive deionization electrodes

“…Carbonaceous materials, such as activated carbons (Choi, 2010;Hou et al, 2012), carbon aerogel (Gabelich et al, 2002), carbon fiber , carbon nanotubes Hou et al, 2014), mesoporous carbon (Tsouris et al, 2011), graphene (Li et al, 2010), hierarchically porous carbons (Mayes et al, 2010;Wen et al, 2012), and mixtures of these materials (Peng et al, 2012;Wang et al, 2014) are potential CDI electrodes because of their favorable conductivity and high surface area. Currently, manufacturing carbon electrodes at low costs is essential for promoting CDI technology.…”
