Cu2O/TiO2 photocatalyst on glass substrate and preparation method and application of Cu2O/TiO2 photocatalyst

Abstract

The invention discloses a Cu2O / TiO2 photocatalyst on a glass substrate and a preparation method and application of the Cu2O / TiO2 photocatalyst. The Cu2O / TiO2 photocatalyst consists of the following components in percentage by weight: 0.1 to 50 percent of Cu2O and the balance of TiO2. The preparation method is simple; raw materials are single; the cost is relatively low; equipment cannot be corroded; the raw materials are readily available; the recycling rate is high; the Cu2O / TiO2 photocatalyst is relatively high in degrading rate when being applied to photocatalysis of methylene blue solution; secondary pollution can be avoided; and the Cu2O / TiO2 photocatalyst is suitable for industrial production and application and has a relatively good market prospect.

Description

technical field

[0001] The invention relates to a Cu on a glass substrate 2 O / TiO 2 Preparation method of visible light catalyst. Background technique

[0002] With the rapid development of social industrial production, a large number of pollutants continue to enter the natural world, bringing pollution to the living environment of human beings that cannot be ignored. Improving the living environment of human beings and eliminating organic pollutants in water is an urgent task for human beings. There are many traditional sewage treatment methods, but most of them have poor mineralization ability to organic pollutants and are easy to cause secondary pollution. At present, these waste water cannot be effectively treated. Nowadays, with the development requirements of society, many emerging water treatment methods have emerged. Among them, the heterogeneous photocatalytic oxidation method has become a current research hotspot because of its outstanding advantages such as bei...
