Embodiment 1
[0029] Weigh out 2 g of copper oxide nanoparticles and place them into a sintered boat (6 cm long, 3 cm wide, and 1.5 cm high). When the muffle furnace was heated to 800 °C, the sintered boat filled with copper oxide nanoparticles was transferred into the muffle furnace for 20 min. Immediately after opening the muffle furnace, the sintering boat was taken out, and the copper oxide nanoparticles were immersed in 40 mL of absolute ethanol at room temperature for rapid quenching. Finally, the quenched copper oxide nanoparticles were filtered, and then dried at 800° C. for 3 hours to obtain treated copper oxide nanoparticles.

Abstract
A method for improving the photocatalytic activity of copper oxide comprises the following steps: heating the copper oxide to enable the temperature of the copper oxide to reach 750-850 DEG C; puttingand completely soaking the copper oxide into absolute ethyl alcohol for rapid quenching treatment, and enabling oxygen atoms on the surface of the copper oxide to be consumed by the absolute ethyl alcohol in order to make oxygen vacancies formed in the surface of the copper oxide; and then filtering, taking out the copper oxide, and drying for 2-4 hours at the temperature of 75-85 DEG C to finishthe treatment of the copper oxide so as to obtain the copper oxide with oxygen vacancies on the surface. The absolute ethyl alcohol is adopted to carry out rapid quenching treatment on the copper oxide, so that a large number of high-concentration oxygen vacancies are formed on the surface of the copper oxide, the photocatalytic performance of the copper oxide is effectively improved, the surfaceactivity is improved, and the copper oxide can be used as a degradation catalytic material of organic pollutants to effectively degrade the organic pollutants.
Description
technical field [0001] The invention relates to a treatment of copper oxide, in particular to a method for improving the photocatalytic activity of copper oxide. Background technique [0002] In recent years, rapid industrialization has led to alarming levels of pollution of heavy metals, toxic organic pollutants (such as dyes) and harmful chemicals in water bodies, which pose serious threats to the environment and human health, with far-reaching consequences. Especially for organic pollutants, its degradation is still a great challenge, and photocatalysis is considered as a promising degradation method, so efforts to remove organic pollutants by photocatalysis are increasing. Due to the extraordinary properties of copper oxide semiconductor nanomaterials, its photocatalytic degradation of organic dye pollutants under ultraviolet or visible light has attracted extensive attention. [0003] Especially transition copper oxides, such as TiO2 and ZnO, are considered to be very ...
