Designing of NiMn-MOF@MXene nanorods@AC@NF electrode material for high performance electrochemical based energy storage devices

MXene, a highly competent material, has great potential for use in emerging supercapacitor devices. The MXene nanosheets establish a two-dimensional (2D) conducting network, enhancing stability and facilitating rapid charge movement at interfaces. In this research, the NiMn-MOF nanocomposite is synthesized using the hydrothermal method and doped with MXene to enhance it's the electrochemical characteristics. The NiMn-MOF@MXene nanocomposite electrode demonstrated a specific capacity of 1289.7 C/g in a 3-electrode assembly, at a current density of 1.3 A/g. In addition, the NiMn-MOF@MXene@AC asymmetric device demonstrated an exceptional energy density of 74.4 W h/kg while operating at a power density of 3120 W/kg. The NiMn-MOF/MXene demonstrated exceptional long-term cycling stability, retaining 92 % of its original specific capacitance after 5000 cycles at a current density of 2.8 A/g. Moreover, the hybrid device showed a small value of IR drop (0.45) after the 5000 cycles. Besides, the hybrid device is used for the detection of hydrogen peroxide in the cancer cells. The purpose of this study is to provide a straightforward and effective method for the production of high-performance energy storage devices that are based on metal organic framework and MXene electrodes.
