Nitrogen-doped reduced graphene oxide-Ni(OH)2-built 3D flower composite with easy hydrothermal process and excellent electrochemical performance Original Research Article Electrochimica Acta, Available online 16 June 2014, Pages Huidi Liu, Jinglin Zhang, Bin Zhang, Lei Shi, Shaozao Tan, Langhuan Huang
Graphical abstractA composite based on nitrogen-doped reduced graphene oxide and Ni(OH)2 is prepared by an easy two-step hydrothermal method. With the enhanced electrochemical activity upon nitrogen doping and the unique three-dimensional flower structure, the obtained composite exhibits high capacitance, excellent rate capability, good cycle life, etc.
