Embodiment 1
[0026] Embodiment 1: The preparation method of this nickel hydroxide composite cobalt ruthenium oxide nanomaterial specifically comprises the following steps:
[0027] (1) In a 100mL beaker, prepare 40mL of a mixed aqueous solution of 0.10mol / L nickel chloride, 0.002mol / L cobalt nitrate, and 0.005mol / L ruthenium nitrate, and add dropwise a mass percent concentration of 12.5% ammonia solution under magnetic stirring 40mL, stirred for 15min to turn the solution from light green to blue-green, and finally to a blue solution to obtain the reaction mixture;
[0028](2) Add the reaction mixture into a 100mL polytetrafluoroethylene-lined reactor, seal the reactor, then put it in an oven at 200°C for 12 hours, let it cool to room temperature, take it out and filter it with distilled water Washing 3 times, and then washing 3 times with absolute ethanol, put the nickel hydroxide composite cobalt ruthenium oxide nanomaterial in a constant temperature box at 60°C for 12 hours to prepare...

[0029] Embodiment 2: The preparation method of this nickel hydroxide composite cobalt ruthenium oxide nanomaterial specifically comprises the following steps:
[0030] (1) Prepare 0.10mol / L nickel chloride, 0.0035mol / L cobalt chloride, 0.0025mol / L ruthenium chloride mixed ethanol solution 40mL in a 100mL beaker, then under magnetic stirring, dropwise add mass percent concentration of 10% KOH aqueous solution 40mL, stirred for 25min to turn the solution from light green to blue-green, and finally to a blue solution to obtain the reaction mixture;
[0031] (2) Add the reaction mixture into a 100mL polytetrafluoroethylene-lined reactor, seal the reactor, then put it in an oven at 160°C for 12 hours, let it cool down to room temperature, take it out for suction filtration, and wash it with distilled water during suction filtration 3 times, and then washed 3 times with absolute ethanol, and the cleaned material was placed in a constant temperature box at 60°C for 12 hours to prepar...
Embodiment 3
[0032] Embodiment 3: The preparation method of this nickel hydroxide composite cobalt ruthenium oxide nanomaterial specifically comprises the following steps:
[0033] (1) Prepare 40 mL of a mixed methanol solution of 1 mol / L nickel phosphate, 0.1 mol / L cobalt phosphate, and 0.01 mol / L ruthenium phosphate in a 100 mL beaker, then add dropwise NaOH with a mass percentage concentration of 1% under magnetic stirring 40mL aqueous solution, stirred for 30min, the solution changed from light green to blue-green, and finally turned into a blue solution to obtain the reaction mixture;
[0034] (2) Add the reaction mixture into a 100mL polytetrafluoroethylene-lined reactor, seal the reactor, then put it into an oven at 80°C for 16 hours, let it cool down to room temperature, take it out for suction filtration, and wash it with distilled water during suction filtration 3 times, and then washed 3 times with absolute ethanol, the cleaned material was placed in an incubator at 80°C for 2 h...
