摘要: Abstract Hollow NiCo2O4 nanoparticle/graphene composite was firstly fabricated by a template-free method via hydrothermal route combined with two-step annealing treatment in N2 and air atmosphere, respectively. The structure morphology of the were studied XRD, XPS, FE-SEM TEM. As supercapacitor electrode material, hollow showed high specific capacitance (1238 F g−1 at 1 A g−1) excellent cycle stability. electrochemical performance may be ascribed to synergistic effect between conductive graphene nanoparticle. This work that should promising material for supercapacitors.
