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
