Embodiment 1
[0040] Preparation of iron cobalt oxide / carbon nitrogen / multi-wall carbon nanotube complex:
[0041] 0.02mol fecl 3 , 0.02mol CoCl 2 , 0.1mol sodium citrate is added to 100 ml of deionized water, ultrasound to it completely dissolved, resulting in FECL 3 -COCL 2 - Sodium citrate aqueous solution, i.e., solution A.
[0042] 0.1 g of multi-wall carbon nanotubes and 0.1 g of aniline were added to a mixed solution of 25 ml of deionized water / 25 ml ethanol, and the carbon nanotubes were uniform, and the carbon nanotubes were dispersed uniform, and the suspension B was dispersed at room temperature.
[0043] 10 ml of solution A was mixed with 50 ml suspension B, and the solution C was obtained at room temperature. Under continuous ultrasound conditions, 3G KBH is slowly added to the solution C. 4 The reaction process was kept at least 2 hours until there was no bubble in the solution to obtain a solution D.
[0044] The solution D was purified by filtration using deionized water a...
Embodiment 2
[0046] Preparation of iron nickel oxide / carbon nitrogen / multi-wall carbon nanotube complex:
[0047] The preparation process of this embodiment is substantially the same as in Example 1, and the difference is that the metal salt is 0.03 mol Nicl. 2 And 0.01mol Fecl 3 The temperature of the complex reaction is 45 ° C. See Figure 4 It can be seen that the obtained iron-nickel oxide has a size of approximately 300 nm and is loaded on the surface of the carbon nanotube.
Embodiment 3
[0049] Preparation of cobalt nickel oxide / carbon nitrogen / multi-wall carbon nanotube complex:
[0050] The preparation process of this embodiment is substantially the same as in Example 1, and the metal salt is 0.02 mol Nicl, respectively. 2 And 0.02mol CoCl 2 The temperature of the complex reaction was 40 ° C. See Figure 5 and Figure 6 It can be seen that the obtained cobalt nickel oxide is from about 100 to 300 nm, which is loaded on the surface of the carbon nanotube.
