高电化学性能三维网状氮掺杂石墨烯的制备
Synthesis of 3D N-doped Graphene Netw orks with High Electrochemical Performance
摘要
Abstract
3D nitrogen‐doped graphene (NRG) was prepared in the hydrothermal method with graphene oxide (GO) as the raw material and melamine as the nitrogenous source and reducing agent .Scanning electron microscopy , X‐ray photoelectron spectroscopy ,Raman spectroscopy ,nitrogen adsorption‐desorption analysis and electrochemical measurements were used to characterize the morphology ,structure ,components and supercapacitor performance of as‐prepared electrode materials .The results showed that GO could be reduced efficiently by melamine and realized N‐do‐ping at the same time .The 3D structure was built due to the strong interaction between graphene sheets .Its content of nitrogen atoms was 4 .37% .The electrochemical performance was measured through electrochemical tests .When the mass ratio of GO and melamine was 1∶2 (NRG‐2) ,the highest specific capacitance of 296 F/g can be achieved at the current density of 1 A/g ,which was higher than the capacitance of other mass ratios of GO and melamine .88 .5%of the capacitance of NRG‐2 remained after 1000 cycles ,which meant that NRG‐2 had a long life cycle .关键词
