We have successfully developed a MOF-based (Co-3[Fe(CN)(6)](2)center dot 10H(2)O) strategy to synthesize Co-Fe mixed metal oxide (Co3O4/Fe2O3) nanocubes (denoted as CFNC). The obtained CFNC is applied as both anode and cathode for high-performance symmetric supercapacitors, exhibiting high energy density of 35.15 W h kg(-1) at a power density of 1125 W kg(-1) as well as excellent stability. Meanwhile, when CFNC is used as electrocatalyst for oxygen evolution reaction (OER), it requires a low overpotential of 310 mV to achieve a current density of 10 mA cm(-2) and exhibited excellent stability.
