Abstract

The invention discloses a preparation method of CuCl / Cu2O / Cu porous nanosheets and an obtained product. The preparation method of the CuCl / Cu2O / Cu porous nanosheets comprises the steps that copper chloride, NaHCO3 and EDTA-2Na are added into a mixed solvent of glycerol and ethyl alcohol and stirred, so that a transparent solution is obtained; and the transparent solution is subjected to the solvothermal reaction, an obtained product is centrifuged and washed, and thus a finished product is obtained. According to the preparation method of the CuCl / Cu2O / Cu porous nanosheets, by adjusting technological parameters such as a reaction system and solvothermal reaction conditions, grain nucleating and growing processes of CuCl, Cu2O and Cu are controlled under the synergistic effect of a surface active agent, a reducing agent and the like, and thus the CuCl / Cu2O / Cu porous nanosheets with uniform morphology and thicknesses and adjustable apertures are obtained. Adopted raw materials are cheap and extensive, reaction controllability is high, products which are uniform in microtopography, narrow in dimension distribution range and high in yield can be obtained only through the one-step solvothermal reaction, and the preparation method has high application value in the fields such as photocatalysis, catalysis, gas sensitivity and lithium batteries.
