Embodiment 1
[0031] A kind of in-situ preparation method of multi-level carbon-based iron-nickel hydroxide, comprising the steps of:
[0032] (1) Preparation of multilevel carbon-based acicular nanowire / needle arrays:
[0033] a. Put the cut carbon cloth in acetone, sonicate it for 15 minutes, and put it in alcohol for 15 minutes to remove impurities on the surface of the commercial carbon cloth, and rinse it with deionized water until the carbon cloth becomes super hydrophilic and obtains a hydrophilic water carbon cloth;
[0034] b. 6.5g disodium hydrogen phosphate (Na 2 HPO 4 ) and 5.8g sodium dihydrogen phosphate (NaH 2 PO 4 ) was dissolved in 200mL deionized water to obtain a phosphate buffer solution;
[0035] c. Add 1.4 mL of pyrrole to the phosphate buffer solution prepared in step b, and then ultrasonically treat the solution to fully disperse the pyrrole in the solution to obtain an electrodeposition electrolyte;
[0036] d. use the hydrophilic carbon cloth obtained in step...
Embodiment 2
[0041] A kind of in-situ preparation method of multi-level carbon-based iron-nickel hydroxide, comprising the steps of:
