Abstract

Ni-Co MOF-based systems have been proposed as supercapacitor electrode materials because they show high energy capacitance. However, most MOFs have poor electrical conductivity and narrow micropores which limit the diffusion within the pores. To overcome the weakness of this MOF, MOF can be composite with ZnO and Functionalize Carbon (FC) on the system. This study aims to determine the effect of adding Ni-Co MOF in the ZnO-FC-NiCo MOF system on aluminum substrates to the performance of the supercapacitors produced. The Ni-Co MOF was successfully prepared by the reflux method at 140 °C. ZnO and FC materials are mixed with the addition of Ni-Co MOF mass of 10% and 20% of the total mass, with the blending method for 5 hours. Supercapacitors were arranged symmetrically using 0.5M H3PO4 electrolytes. The samples characterization were carried out using XRD, SEM-EDX, Cyclic Voltammetry, and EIS. It is shown that specific capacitance is increasing, ranged from 1.15 to 6.62 F/g.
