[0030] Example 1
[0031] Preparation of CoO@Co-NC / Ketjen Black (KB)
[0032] A two-stage high-temperature synthesis method is adopted. The specific process is as follows: Weigh 1mmol of cobalt acetate tetrahydrate, 5g of urea and 0.25g of Ketjen Black, add 50mL of deionized water, dissolve or disperse by ultrasound for 30min, and evaporate and dry at 80℃ Dry moisture. The obtained precursor mixture was heated from room temperature to 550°C in nitrogen protective gas at a heating rate of 5°C / min for 2 hours; then, the temperature was increased to 700°C at a rate of 5°C / min for 2 hours. Naturally cool to room temperature and take it out to obtain Co@CoO-NC / KB.
[0033] Using X-ray diffractometer (XRD, D8ADVANCE, Cu-Kα, ) Phase analysis of the product; Transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM) characterization of the product through a transmission electron microscope (JEOL-2010, 200kV) to observe the morphology of the product...
