Abstract

The invention discloses a preparation method of CuCl / Cu2O / Cu porous nanosheet and the obtained product. The method is as follows: adding copper chloride, NaHCO3, EDTA-2Na into a mixed solvent of glycerol and ethanol, stirring to obtain a transparent solution, The transparent solution is subjected to solvothermal reaction, and the obtained product is centrifuged and washed to obtain the product. The present invention controls the grain nucleation and growth process of CuCl, Cu2O and Cu by adjusting process parameters such as reaction system and solvothermal reaction conditions, and under the synergistic effect of surfactants, reducing agents, etc., to obtain uniform morphology, thickness and CuCl / Cu2O / Cu porous nanosheets with tunable pore size. The raw materials used in this method are low in price, wide in sources, and highly controllable in reaction. Only one step of solvothermal reaction can obtain products with uniform microscopic morphology, narrow size distribution range, and high yield. Lithium battery and other fields have high application value.
