Embodiment 1
[0032] 1. Pretreatment of conductive carbon cloth
[0033] 1.1 Cut the conductive carbon cloth into a rectangle of 2×4cm. Use acetone, hydrochloric acid, and absolute ethanol to ultrasonically clean for 10 minutes, and dry them for later use.
[0034] The concentration of hydrochloric acid in step 1.1 is 1mol L -1 .
[0035] 2. NiCo on conductive carbon cloth 2 S 4 preparation of
[0036] 2.1 Dissolve an appropriate amount of ammonia water and o-phenanthroline in deionized water, stir evenly, add a certain proportion of cobalt nitrate hexahydrate and nickel nitrate hexahydrate, and stir evenly.
[0037] 2.2 Add an appropriate amount of thiourea to the above solution, and stir magnetically for 30 minutes.
[0038] 2.3 Transfer the solution described in 2.2 into a high-pressure reactor, and put it into the conductive carbon cloth treated in step 1.1, heat it for a certain period of time, cool it down to room temperature naturally, separate the precipitate by centrifugation...
