Abstract

The invention relates to a method for preparing nano cuprous oxide powder based on an ion exchange process. The method comprises the following steps: respectively reacting copper salt solutions with different concentrations with cation exchange resin in a pneumatic stirring device for 0.5-3 hours, obtaining a copper-based precursor through an ion exchange path, preparing uniformly dispersed copper hydroxide gel, adding 10-300mL of the gel into a reactor, and reacting with a reducing agent glucose for 0.5-2 hours at the reaction temperature of 70-90 DEG C and the pH value of a reaction system of 10-11; and taking out the product after the reaction is completed, centrifuging, filtering, cleaning with absolute ethyl alcohol, and drying in vacuum to obtain the cuprous oxide nanoparticles. With application of the ion exchange technology, generated copper hydroxide gel can be effectively dispersed in a pneumatic stirring mode, the copper-based precursor is effectively modified through the mechanochemical effect, and agglomeration in the follow-up nano-cuprous oxide preparation process is prevented; operation is simple, conditions are mild and the process is short.

Description

Technical field: [0001] The invention belongs to the fields of chemical engineering and nano functional materials, and in particular relates to a method for preparing cuprous oxide nanomaterials based on an ion exchange process. Background technique: [0002] Cuprous oxide is a P-type semiconductor material with a bandgap width of 2.17 eV and has strong photocatalytic performance under visible light conditions. It is mainly used in antibacterial, photocatalytic, gas sensing, carbon monoxide oxidation, lithium battery cathode materials and many other fields, and has broad application prospects. The common preparation methods of cuprous oxide include liquid phase reduction method, electrochemical deposition method, template method, sol-gel method and sputtering method. Although these methods can prepare cuprous oxide nanomaterials, there are also problems to a certain extent, such as the poor biocompatibility of the reducing agent in the liquid phase reduction method, the hig...
