Embodiment 1
[0057] (1) Preparation of nickel acetate Ni(CH) with a concentration of 0.05mol / L 3 COO) 2 4H 2 O solution A. Specifically, the Ni(CH 3 COO) 2 4H 2 O was added to 40mL of deionized water, and stirred for 30min to form a uniformly mixed solution A;
[0058] (2) The solution A is charged into a polytetrafluoroethylene-lined high-pressure reactor, and the volume filling ratio is kept at 40%.
[0059] (3) Take a 50mL beaker, completely immerse foam copper with a length of 6cm and a width of 1cm in acetone, 3mol / L HCl solution, deionized water, and absolute ethanol in sequence, and ultrasonically treat them for 30min respectively. Put the treated foam copper into the polytetrafluoroethylene reactor containing solution A; put the sealed reactor into the homogeneous hydrothermal reactor, set the temperature parameter to 160°C, and the reaction time to 12h;
[0060] (4) Cool to room temperature after the reaction, take out the reacted copper foam and wash with absolute ethanol ...
