Abstract：

Presented　in　this　report　is　a　new,　simple　and　effective　method　for　synthesizing　hierarchical　dumbbell-shaped　CeO　2　derived　from　a　Ce-BTC　MOF　at　room　temperature.　The　product　was　characterized　using　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　Fourier　transform　infrared　spectroscopy　(FTIR)　and　Raman　spectroscopic　measurements.　When　used　as　an　electrode　in　a　supercapacitor　with　a　KOH　electrolyte　and　a　K　4　Fe(CN)　6　redox-active　additive,　the　capacitor　exhibited　large　a　specific　capacitance,　high　rate　capability　and　good　cycling　stability.　Capacitances　of　779　and　501 F g　−1　were　achieved　at　rates　of　1　and　15 A g　−1　.　Simultaneously,　the　capacity　retention　was　maintained　at　nearly　91%　after　10000　cycles.　©　2016　Elsevier　Ltd
