Embodiment 1
[0038] A method for synthesizing cuprous oxide micron hollow spheres, comprising the following steps:
[0039] (1) Weigh 0.002mol of copper nitrate (analytical grade) and add it into the mixed solution of water and organic solvent (40 ml of ethylene glycol, 1 ml of deionized water), stir until completely dissolved, and obtain a light blue transparent liquid;
[0040] (2) Transfer the solution described in step (1) into the liner of a 50 ml polytetrafluoroethylene hydrothermal kettle, put on a steel sleeve, put it into an oven that has been heated to 60 °C in advance, and set the reaction temperature to 180 °C ℃, keep warm for 60 minutes after reaching the reaction temperature, and then cool naturally;
[0041] (3) The brick-red turbid liquid obtained in step (2) was centrifuged (5000 r / m), and the obtained brick-red solid was washed with ethanol and dried in an oven at 40°C to obtain cuprous oxide micron hollow spheres.
[0042] The product obtained in this example was determ...
