Embodiment 1
[0039] (1) 0.616g ammonium fluoride was dissolved in 40mL 2mmol L -1 Stir in nickel nitrate solution for 30min to obtain solution A;
[0040] (2) Transfer solution A into a reaction kettle with a piece of carbon cloth (2cm×3cm), and react at 150°C for 6h. After the reaction, take out the carbon cloth, wash it with a large amount of deionized water, and dry it in an oven at 50°C for 8h. Heat treatment in nitrogen at 450°C for 2 hours to obtain NiO nanosheet / carbon cloth composite material;
[0041] (3) the obtained in step (2) in 0.05mol L -1 Immerse in potassium permanganate solution at 16°C for 24h, take it out and wash it with deionized water, and then heat-treat at 400°C for 1h to obtain MnO 2 Nanowire / NiO nanosheet / carbon cloth ternary structure electrode material.
[0042] (4) In the three-electrode system, directly use the obtained ternary structure electrode material as the working electrode, use the platinum electrode as the counter electrode, and use the saturated ...
