Hierarchical Co3O4@NiCoLDH nanosheets (NSs) were prepared on carbon cloth through a multistep method,containing Metal-organic frameworks (MOF)-templated thermal annealing and electrodeposition.The triangle-shaped Co3O4NSs were firstly obtained by thermal treatment of MOF templates in air.Then,ultrathin NiCoLDHNSs were in-situ electrodeposited on the surface of Co3O4NSs,constructing a core-shell structure.Benefiting the unique hierarchical structure,high conductivity of Co3O4NSs core and large surface area of NiCoLDHNSs shell,the Co3O4@NiCoLDHNSs array served as supercapacitor electrode exhibits excellent electrochemical properties,such as high specific capacitance of 1708 F g-1 (850 C g-1) at a current density of 1 A g-1,good rate capability,and excellent cycling stability.Further,the asymmetric supercapacitor assembled by Co3O4@NiCoLDHNSs and activated carbon,also displays superior electrochemical performance with high energy density and power density.Remarkably,the strategy of constructing core-shell structure based on MOF templates could be extended to other electrochemical fields.
