Embodiment 1
[0043] A hollow copper-doped cobalt-nickel oxide-coated nitrogen-doped carbon nanocomposite material comprises a hollow nitrogen-doped carbon material, and the hollow nitrogen-doped carbon material is coated with copper-doped cobalt-nickel oxide. The hollow nitrogen-doped carbon material has a hollow polyhedral structure.
[0044] The preparation method of the nitrogen-doped carbon nanocomposite material coated with hollow copper-doped cobalt-nickel oxide is as follows:
[0045] Step 1: Coat a layer of polyaniline on the surface of ZIF-67 to obtain ZIF-67@polyaniline composite material, and obtain hollow polyaniline by acid etching the obtained ZIF-67@polyaniline composite material:
[0046] Disperse the ZIF-67 powder in 100 mL of water, and disperse uniformly by ultrasonic for 20 min to obtain a dispersion liquid, the concentration of ZIF-67 is 1 mg / mL. Then 20 μL of aniline (Sigma-Aldrich) monomer was added into the above dispersion liquid to make it uniformly dispersed. S...
