Embodiment 1
[0028] Example 1 Preparation of nitrogen-doped carbon nanotube-wrapped iron-cobalt alloy composite (FeCo-NCNTs)
[0029] Dissolve the metal salt and dicyandiamide with a molar ratio of 1:30 in deionized water, wherein the metal salt only contains iron nitrate and cobalt nitrate and the molar ratio of the two is 1:10, ultrasonically mix evenly, and then dry and grind to prepare have to The precursor is placed in a high-temperature tube furnace under a nitrogen atmosphere, and the temperature is raised and roasted in programmed stages. The temperature of the first stage of roasting is 500°C, the roasting time is 3h, and the heating rate is 2°C / min; the temperature of the second stage of roasting is 700°C ℃, the calcination time is 4h, and the heating rate is 5℃ / min. After the temperature of the tube furnace dropped to room temperature, the sample was taken out for grinding to obtain a black powder.
[0030] The obtained samples were placed in a beaker with dilute sulfuric ac...
