Li-ion doped graphene/carbon nanofiber porous architectures for electrochemical capacitive desalination

Abstract Large-scale Li-ion doped graphene/carbon nanofiber porous architectures were prepared by electrospinning homogeneous LiNO 3 /graphene oxide/polyacrylonitrile nanofibers, followed by carbonization at 900 °C. Capacitive de-ionization was measured in a dynamic mode. The architectures show excellent electrical adsorption, which is enhanced by the incorporation of LiC 6 and graphene with a higher electro-adsorption capacity and a faster adsorption rate due to the large surface area (393.64 m 2  g − 1 ) and good conductivity.
