Embodiment 1
[0030] (1) configuration solution, weigh ammonium molybdate ((NH 4 ) 6 Mo 7 o 24 ) 80mg, weighed 30mg of dopamine hydrochloride, added to 15mL deionized water respectively, fully oscillated and stirred to make it evenly dissolved;
[0031] (2) Cut the nickel foam into a rectangular sheet of 1*2.2 cm, shake and clean it in 3mol / L hydrochloric acid for 30 minutes to remove the surface oxide film, and then wash it 5 times with water and ethanol;
[0032] (3) Put the configured solution in a 15ml polytetrafluoroethylene-lined reactor, then place the cut foam nickel sheet vertically in the center of the lining, and place the reactor at 150°C for 8 hours of reaction; Afterwards, the reactor was naturally cooled, and the nickel foam sample was taken out and washed repeatedly with deionized water and ethanol, and dried in a 60° oven to obtain a high-efficiency electrolytic water hydrogen evolution catalyst precursor;
[0033] (4) Put the precursor in the corundum boat and place it...
