Embodiment 1
[0024] In this embodiment, a bimetallic coordination polymer electrode material M Co / Ni -The preparation method of CPs-1, the steps are as follows:
[0025] a. Add nickel nitrate hexahydrate and trimesic acid into the solvent N,N-dimethylformamide respectively, and stir at room temperature for 30 minutes to fully dissolve the solutes to obtain solutions A and B respectively; then drop Add solution A to solution B, and magnetically stir again for 30 minutes to obtain solution C; then use a microwave reactor at 150°C to conduct the first microwave reaction of solution C for 30 minutes to obtain monometallic coordination polymer M Ni -CPs-1;
[0026] b. adding cobalt nitrate hexahydrate to the M obtained in step a Ni - in the N,N-dimethylformamide solution of CPs-1, and then perform magnetic stirring. After stirring for 30 minutes, the reactant mixture is obtained. Using a microwave reactor, at 150 ° C, the solution C is subjected to the second Microwave reaction for 30 minute...
Embodiment 2
[0036] This embodiment is basically the same as Embodiment 1, especially in that:
[0037] In this embodiment, a bimetallic coordination polymer electrode material M Co / Ni -The preparation method of CPs-2, the steps are as follows:
[0038] a. Add nickel nitrate hexahydrate and trimesic acid into the solvent N,N-dimethylformamide respectively, and stir at room temperature for 10 minutes to fully dissolve the solutes to obtain solutions A and B respectively; then drop Add solution A to solution B, and magnetically stir again for 10 minutes to obtain solution C; then use a microwave reactor at 120°C to conduct the first microwave reaction of solution C for 10 minutes to obtain monometallic coordination polymer M Ni -CPs-2;
[0039] b. adding cobalt nitrate hexahydrate to the M obtained in step a Ni - in the N,N-dimethylformamide solution of CPs-2, and then perform magnetic stirring. After stirring for 10 minutes, the reactant mixture is obtained. Using a microwave reactor, at...
