摘要：

The pursuit of meeting global energy demands, along with the depletion of fossil fuels and related environmental concerns, has led to the development of supercapacitors. Among various components of supercapacitors, electrode material plays a crucial role in their performance. Bimetallic Metal-Organic Framework (MOF) has attracted the attention of researchers as a supercapacitor electrode material owing to its large surface area, tunable porous structure, rich active sites, and ease of synthesis. Incorporation of transition metal oxides in MOF can result in further amplification of electrochemical performance. Here, we synthesized MnO2@Zn/Ni-MOF using the solvothermal method. Various physical and electrochemical analytical techniques were used for the characterization of fabricated electrode material. The MnO2@Zn/Ni-MOF exhibited a specific capacitance of 1537 Fg(-1) at 2 Ag-1, which is higher than that of pristine Zn/Ni-MOF (1185 Fg(-1) at 2 Ag-1). MnO2@Zn/Ni-MOF also retained 89% of its original capacitance at 6 Ag-1 after performing 4000 cycles, signifying its appropriateness for supercapacitor application.
