Embodiment 1

[0044] Deploy 0.05M copper sulfate (CuSO 4 .5H 2 O) solution and heated to 65 °C. Then, at the same temperature, ethylenediamine was added to the copper sulfate solution and stirred to form a mixed solution. Here, the concentration of ethylenediamine in the mixed solution is 0.05M. Subsequently, sodium bisulfite and sodium sulfide were added in sequence, and reacted at 65° C. for about 5 seconds. Here, the reaction concentrations of sodium bisulfite and sodium sulfide are both 0.05M. After the reaction, filter, wash with deionized water, and finally dry to obtain a powdery product.

Embodiment 2

[0046] Deploy 0.5M copper sulfate (CuSO 4 .5H 2 O) solution and heated to 75 °C. Then, at the same temperature, ethylenediamine was added to the copper sulfate solution and stirred to form a mixed solution. Here, the concentration of ethylenediamine in the mixed solution is 0.5M. Subsequently, sodium bisulfite and sodium thiosulfate were added in sequence, and reacted at 75° C. for about 3 minutes. Here, the reaction concentrations of sodium bisulfite and sodium thiosulfate were both 0.5M. After the reaction, filter, wash with deionized water, and finally dry to obtain a powdery product.

Embodiment 3

[0048] Deploy 1.0M cuprous chloride (CuSO 4 .5H 2 O) solution and heated to 95°C. Then, at the same temperature, ethylenediamine was added to the cuprous chloride solution and stirred to form a mixed solution. Here, the concentration of ethylenediamine in the mixed solution is 1.0M. Subsequently, sodium sulfide and sodium thiosulfate were sequentially added, and reacted at 95° C. for about 10 minutes. Here, the reaction concentrations of sodium sulfide and sodium thiosulfate are both 1.0M. After the reaction, filter, wash with deionized water, and finally dry to obtain a powdery product.

[0049] The present invention measures the product microstructure that above-mentioned technique makes with scanning electron microscope (SEM), and its result is as follows figure 1 and figure 2 shown. Depend on figure 1 and figure 2 It can be observed that the above preparation process can produce porous copper sulfide Cu x S (x is 1 to 2) nano-micron hollow spheres with a diamet...

Description

technical field [0001] The invention relates to a porous copper sulfide nano-micron hollow sphere and a preparation method thereof, in particular to a porous copper sulfide nano-micron hollow sphere suitable for increasing the specific surface area and a preparation method thereof. Background technique [0002] Copper sulfide is a forward-looking optoelectronic material, which has broad application prospects in solar cells, electrochemical cells, infrared light detectors, catalysts, etc. Based on the wide application of copper sulfide materials, many researchers have carried out in-depth research on it. At room temperature, there are five phases of copper sulfide CuxS, x is 1 (covellite), 1.75 (orthorhombic azurite, anilite), 1.8 (blue chalcocite, digenite), 1.95 (covellite ore, djurleite), 2 (chalcocite, chalcosite). In addition, with the development and wide application of nano-micro technology, the preparation of copper sulfide with nano-micro structure has gradually at...
