A kind of preparation method of nanometer cuprous oxide catalyst

Abstract

The invention provides a method for preparing a nanometer cuprous oxide catalyst, which includes the following steps: S1. Dissolve the copper source in distilled water, and then add a strong alkaline solution thereto to obtain copper hydroxide precipitation; S2. In the prepared Add glucose to the copper hydroxide precipitation; S3. Add [Emim]Br (1-ethyl-3-methylimidazole bromide) to the mixture obtained in step S2; S4. Add the mixture obtained in step S3 under water bath conditions. The mixture is incubated to obtain cuprous oxide; S5, clean the prepared pure cuprous oxide nanoparticles, and then vacuum-dry the cuprous oxide nanoparticles. The preparation method of nanometer cuprous oxide catalyst provided by the invention has mild reaction conditions and is environmentally friendly, and the cuprous oxide prepared by the method of the invention has different morphologies and good photocatalytic performance.

Description

technical field

[0001] The invention relates to a preparation method of a nano cuprous oxide catalyst. Background technique

[0002] In the field of modern nanotechnology, nanomaterials have attracted people's attention because of their excellent physical and chemical properties, especially in the field of structure and control of nanomaterials. Nanomaterials have broad application prospects in the fields of optics, catalytic science, and electrochemistry.

[0003] Cuprous oxide is an important P-type semiconductor with a direct bandgap of 2.17eV. It is widely used in solar energy conversion, photocatalysis, lithium-ion battery electrodes, and magnetic storage devices. In addition, cuprous oxide is also an ideal material for studying the shape evolution of microcrystalline materials and nanocrystals.

[0004] At present, people are trying to study the morphology control of cuprous oxide in the synthesis process. The morphology structure includes regular octahedral structur...
