Rodlike CeO2/carbon nanocomposite derived from metal-organic frameworks for enhanced supercapacitor applications
The rod-shaped CeO2@C architectures have been synthesized by novel and facile methods initially from metal-organic frameworks (MOFs). The MOF-derived material showed a pseudocapacitance of 1102 F g(-1) at 2 A g(-1) and 418 F g(-1) at a high current density of 20 A g(-1) and had excellent cyclic stability of about 2.3% decrease after 5000 cycles. Results revealed that favorable effects of dispersed partially graphitic carbon in the CeO2@C composite could improve electronic conductivity, which made this product be an alternative high-performance electrode for supercapacitors.
