Self-assembled N/S codoped flexible graphene paper for high performance energy storage and oxygen reduction reaction

Journal Article


Abstract


  • A novel flexible three-dimensional (3D)

    architecture of nitrogen and sulfur codoped graphene has

    been successfully synthesized via thermal treatment of a liquid

    crystalline graphene oxide−doping agent composition, followed

    by a soft self-assembly approach. The high temperature

    process turns the layer-by-layer assembly into a high surface

    area macro- and nanoporous free-standing material with

    different atomic configurations of graphene. The interconnected

    3D network exhibits excellent charge capacitive performance of 305 F g−1 (at 100 mV s−1), an unprecedented volumetric

    capacitance of 188 F cm−3 (at 1 A g−1), and outstanding energy density of 28.44 Wh kg−1 as well as cycle life of 10 000 cycles as a

    free-standing electrode for an aqueous electrolyte, symmetric supercapacitor device. Moreover, the resulting nitrogen/sulfur

    doped graphene architecture shows good electrocatalytic performance, long durability, and high selectivity when they are used as

    metal-free catalyst for the oxygen reduction reaction. This study demonstrates an efficient approach for the development of

    multifunctional as well as flexible 3D architectures for a series of heteroatom-doped graphene frameworks for modern energy

    storage as well as energy source applications.
