Embodiment 1
[0039] A preparation method of hydrogen evolution electrocatalytic material Pt-CoP is as follows:
[0040] (1) Pour 7.5mL of aqueous solution dispersed with 75mg of polyvinylpyrrolidone and 65mg of squaraine into 2.5mL of methanol solution of 141.2mg of cobalt nitrate, sonicate for 1min, let stand for 72h, wash with water three times, and centrifuge at 8000rpm for 5min , freeze-dried to obtain a pink powder;
[0041] (2) Place the pink powder prepared in (1) in argon, then raise the temperature to 400°C at 1°C / min, and keep it warm for 2h to obtain the precursor powder;
[0042] (3) Take 0.05g of the precursor powder and 0.8g of sodium hypophosphite prepared in (2) and place them in argon, and place the precursor powder at the gas outlet of the tube furnace, below the sodium hypophosphite. Then the temperature was raised to 350°C at 5°C / min, and kept for 2 hours to obtain a black powder CoP;
[0043] (4) Take 25 mg of the black powder prepared in (3) and disperse it in 2.5 m...
