Embodiment 1
[0021] Take 50 ml of ethylene glycol, 0.05 g of polyvinylpyrrolidone (PVP), and 2 ml of 0.1 mol / L copper acetate solution in a beaker, and stir for 10 min to obtain a blue and transparent mixed solution; under stirring conditions, in the above mixed solution Add 2 ml of 0.2 mol / L sodium hydroxide solution dropwise, continue to stir for 5 min, transfer the resulting suspension to a three-necked flask, and react for 10 min at 150 °C under the condition of microwave power 800 W to obtain oxalic acid Green precipitate; the precipitate was washed twice with water and twice with alcohol, and dried in a vacuum oven at 60°C for 5 h to obtain grass-green cuprous oxide nanowire powder.
[0022] See attached figure 1 , which is the transmission electron microscope (TEM) image of the cuprous oxide nanowires prepared in this example: by figure 1 It can be seen that the radial size of the cuprous oxide nanowires is about 20 nm.
[0023] See attached figure 2 , which is the X-ray diffrac...
Embodiment 2
[0025] Take 50 ml ethylene glycol and 2 ml 0.1 mol / L copper acetate solution in a beaker, stir for 10 min to obtain a blue transparent mixed solution; under stirring conditions, add 2 ml 0.2 mol / L copper acetate dropwise to the above mixed solution Sodium hydroxide was dissolved, and after stirring for 5 min, the resulting suspension was transferred to a three-necked flask, and reacted at 170°C and 800 W for 8 min to obtain a grass-green precipitate. The precipitate was washed twice with water and twice with alcohol, and dried in a vacuum oven at 60°C for 5 h to obtain grass-green cuprous oxide nanowire powder.
[0026] See attached image 3 , which is a transmission electron microscope (TEM) image of the cuprous oxide nanowires prepared in this example.
