Embodiment 1
[0033] In the present embodiment, graphene oxide loaded copper sulfide composite material is realized according to the following steps:
[0034] (1) Weigh 1g graphene oxide, 1g copper nitrate and 1g sodium sulfide and dissolve in ethanol solvent, then transfer the solution to a sealed beaker, stir on a magnetic stirrer, the stirring rate is 350rpm, after stirring for 6h, Promptly make mixed solution;
[0035] (2) Transfer the mixed solution obtained in step (1) to a hydrothermal reaction kettle, and then place the hydrothermal reaction kettle in an oven for hydrothermal reaction. The temperature of the oven is set at 160° C., and the reaction time is 3 hours;
[0036] (3) The hydrothermal reaction product obtained in step (2) is subjected to centrifugal cleaning in a centrifuge, the centrifugal speed is 6000rpm, the number of centrifugals is 8 times, and the centrifugal solvent is ultrapure water; then the product is placed in a drying oven to dry , the drying temperature is ...
Embodiment 2
[0039] In this embodiment, the graphene oxide-supported copper sulfide composite material is realized by the following steps:
[0040] (1) Weigh 8g of graphene oxide, 1g of copper nitrate and 1g of sodium sulfide and dissolve them in ultrapure water, then transfer the solution to a sealed beaker and stir on a magnetic stirrer at a stirring rate of 400rpm, after stirring for 7h , to obtain a mixed solution;
[0041] (2) Transfer the mixed solution obtained in step (1) to a hydrothermal reaction kettle, and then place the hydrothermal reaction kettle in an oven for hydrothermal reaction. The temperature of the oven is set at 200° C., and the reaction time is 10 hours;
[0042] (3) The hydrothermal reaction product obtained in step (2) is subjected to centrifugal cleaning in a centrifuge, the centrifugal speed is 7000rpm, the number of centrifugals is 9 times, and the centrifugal solvent is ethanol; then the product is placed in a drying oven to dry and dry The temperature is 45...
