High-performance supercapacitors require electrodes featuring a high surface area, suitable porosity, and conductivity. Metal-organic frameworks (MOFs) hold a high surface area and suitable porosity while insufficient conductivity. Herein, a single-step chemical strategy was developed to directly synthesize a composite of copper-nickel rubeanate MOF and highly conductive reduced graphene oxide (rGO) nanosheets (CNRG-MOF) on nickel foam (CNRG-MOF/NF) electrode. The nanocomposite enables it to use as a high-performance supercapacitor electrode. The bimetallic CNRG-MOF/NF electrode exhibits superior electrochemical performance than its single metallic counterparts. The optimized CNRG-MOF/NF electrode represents a high specific capacitance of 846.15 F g⁻¹ at a current density of 1.0 A g⁻¹. A three-electrode system exhibited up to 96.37 % capacitance retention after 7000 galvanostatic charge-discharge (GCD) cycles, indicating its excellent stability. These results may pave the way for the direct use of MOF materials for electrochemical energy devices instead of pyrolyzing the MOFs to improve the conductivity while losing controllable structural merits. GCD curve was obtained at different current densities to evaluate the nanocomposite's asymmetric setup charge storage capability. The electrode capacity for the asymmetric system was measured as 93.3 F g⁻¹, which proves the capacitive property of CNRG-MOF/NF electrode.

高性能超级电容器需要具有高表面积、合适孔隙率和导电性的电极。金属有机框架 (MOF) 具有高表面积和合适的孔隙率，但导电性不足。在此，开发了一种单步化学策略，在泡沫镍（CNRG-MOF/NF）电极上直接合成铜-镍红宝石MOF和高导电还原氧化石墨烯（rGO）纳米片（CNRG-MOF）的复合材料。纳米复合材料使其能够用作高性能超级电容器电极。双金属 CNRG-MOF/NF 电极比其单金属电极表现出优异的电化学性能。^{优化的 CNRG-MOF/NF 电极在 1.0 A g -1}的电流密度下表现出 846.15 F g ^{-1的高比电容}. 三电极系统在 7000 次恒电流充放电 (GCD) 循环后表现出高达 96.37% 的电容保持率，表明其具有出色的稳定性。这些结果可能为直接使用 MOF 材料用于电化学能源装置铺平道路，而不是通过热解 MOF 来提高导电性，同时失去可控的结构优点。在不同电流密度下获得 GCD 曲线以评估纳米复合材料的不对称设置电荷存储能力。非对称系统的电极容量测得为93.3 F g ^-1，这证明了CNRG-MOF/NF电极的电容特性。
