• increased capacitance of 226 F·g−1 at 1 A·g-1 [22]. Xia et al. used a Ti3C2Tx MXene electrode decorated with nickel oxide (NiO) nanosheets. The electrode was synthesized via a hydrothermal method. The electrode used in a supercapacitor showed an excellent specific capacitance of 80 F·g−1 and an energy

• using an ultrasonic cleaner for 15 min to remove dust and impurities from the substrates. Substrates were dried with pure compressed air. The following techniques were used to grow different metal oxide nanostructures. Evaporation–condensation technique: NiO, SnO2, ZnO The growth of nickel oxide (NiO
