چکیده
Abstract A novel poly(3,4-ethylenedioxythiophene)-reduced graphene oxide/copper-based metal–organic framework (PrGO/HKUST-1) has been successfully fabricated by incorporating electrochemically synthesized oxide (PrGO) and hydrothermally copper-based (HKUST-1). The field emission scanning microscopy (FESEM) elemental mapping analysis revealed an even distribution of poly(3,4-ethylenedioxythiophene) (PEDOT), reduced (rGO) HKUST-1. crystalline structure vibration modes PrGO/HKUST-1 were validated utilizing X-ray diffraction (XRD) as well Raman spectroscopy, respectively. remarkable specific capacitance (360.5 F/g) was obtained for compared to HKUST-1 (103.1 F/g), PrGO (98.5 PEDOT (50.8 using KCl/PVA a gel electrolyte. Moreover, composite with the longest charge/discharge time displayed excellent energy (21.0 Wh/kg), power (479.7 W/kg) outstanding cycle life (95.5%) over 4000 cycles. Thus, can be recognized promising storage material.
