[0032] The preparation method of the chalcogenide copper compound micro-nano heterojunction of the present invention, the expression of the element composition of the chalcogenide copper compound micro-nano heterojunction is Cu x S y / CuO is characterized in that: comprising the following steps: a: mixing and heating lye, water-soluble inorganic copper salt and sulfur element; the present invention adopts one-step synthesis, novel and reasonable design, simple process, low cost and simple operation, It is easy to realize the control of the synthesis process and is suitable for industrial production. No surfactant and organic auxiliary agent are used in the preparation process, and non-toxic and conventional raw materials and reagents are used in the reaction process. The production cost is low and the environment is environment-friendly.
[0033] In this embodiment, the expression Cu x S y 1≤x / y≤2 in / CuO, in step a, the reaction temperature is 130-250°C, and the reaction ti...
Embodiment 1
[0052] A method for preparing a chalcogenide copper compound micro-nano heterojunction in this embodiment comprises the following steps:
[0053] a. (1) first add 12 parts of NaOH and 6 parts of deionized water to make lye in the polytetrafluoroethylene container of 25 milliliters by weight, then add 2.15 parts of cupric chloride and 0.35 part of sulfur simple substance, then the The PTFE container is sealed to prevent the evaporation of water;
[0054] (2) Shake the reaction vessel in (1) until the reactants are fully mixed, put it into a muffle furnace and raise the temperature to 220°C, and react for 36 hours;
[0055] b. Take out the reaction vessel and cool it to room temperature, then wash and filter the obtained precipitate with cold deionized water, repeat 6 times until the filtrate is neutral, and collect the precipitate;
[0056] c. Finally, dry the washed precipitate at 60°C, and the obtained product is Cu x S y / CuO micro-nano heterojunction (such as Figure 1 ...
