Embodiment 1
[0027] The preparation method of the CoP / C hierarchical nanowire assembled by nanoparticles comprises the following steps:
[0028] 1) 6mmol CoCl 2 ·6H 2 O was added to 30ml of deionized water, stirred at room temperature for 20min to dissolve;
[0029] 2) Add 3mmol nitrilotriacetic acid to the solution obtained in step 1), and stir at room temperature for 30min to make the solution evenly mixed;
[0030] 3) Add 10 mL of isopropanol to the solution obtained in step 2), and stir at room temperature for 5 hours;
[0031] 4) Transfer the solution obtained in step 3) into a 100mL reactor, and react in an oven at 180°C for 6 hours; take out the reactor, and let it cool down to room temperature naturally;
[0032] 5) Centrifugally filter the product obtained in step 4), repeatedly wash the obtained precipitate with deionized water and absolute ethanol, and dry it in an oven at 70°C to obtain a Co-NTC precursor;
[0033] 6) Take 0.5mmol or 18mmol of sodium hypophosphite from the ...
