Examples
Embodiment 1
[0019] 1) Preparation of Ni complexes
[0020] Soluble nickel salt was dissolved in deionized water / isopropanol mixed system. After dissolving, nitrilotriacetic acid was added and reacted at 120°C for 24 hours. The obtained precipitate was washed and dried to obtain Ni complex.
[0021] 2) Preparation of Ni complex dispersion
[0022] Weigh 0.2g Ni complex into a 250ml beaker, add 100ml deionized water and sonicate for 30min to obtain Ni complex dispersion.
[0023] 3) Preparation of porous polypyrrole tubes
[0024] Put the above-mentioned Ni complex dispersion in an ice-water bath until the temperature drops to 0-5°C, add 0.02ml of pyrrole monomer and stir for 10 minutes, then add 0.6ml of prepared 0.5mol / L (NH 4 ) 2 S 2 o 8 aqueous solution, stirred for 30 min, and the obtained precipitate was cross-washed five times with deionized water and ethanol, and dried at 60° C. for 24 h.
