Embodiment 1
[0019] The invention provides a method for rapidly precipitating two-dimensional nanosheets of basic copper sulfate. The method takes copper sulfate and ammonia water as raw materials, and synthesizes it by liquid phase precipitation method, and its specific operation steps are as follows:
[0020] Step 1, at 25°C, 700g of 0.3% copper sulfate and 300g of 0.09% ammonia were dissolved in water and kept stirring for 10 minutes;
[0021] Step 2, using a high-speed centrifuge to separate the mixed material obtained in step 1 at 4000r / min for 5 minutes;
[0022] Step 3, the light blue precipitate of gained is washed 3 times with 96% ethanol solution;
[0023] Step 4, drying the material obtained in Step 3 at 60° C. for 10 hours to obtain basic copper sulfate two-dimensional nanosheets.
[0024] XRD results such as figure 1 The product structure is basic copper sulfate, the appearance is as follows figure 2 As shown, it is a nano-scale sheet structure, and the width of the nano-...
