As the environment deteriorates, people pay more and more attention to environmental protection. Some traditional organic wastewater treatment methods are difficult to meet the development needs due to the many by-products, complex post-treatment, secondary pollution and other limitations. Photocatalytic oxidation technology has received increasing attention for its outstanding advantages such as low energy consumption, mild reaction conditions, simple operation, and no secondary pollution. 

    Semiconductor photocatalysis means that the semiconductor catalyst generates electron-hole pairs under the action of visible light or ultraviolet light. The O₂, H₂O and pollutant molecules adsorbed on the semiconductor surface accept photo-generated electrons or holes, and a series of redox reactions occur. It’s such a photochemical method to degrade toxic pollutants into non-toxic or less toxic substances. This method can be carried out at room temperature, can use sunlight, has a wide range of catalyst sources, is inexpensive, non-toxic, stable, and recyclable utilization, no secondary pollution and other advantages. Currently, most photocatalysts that degrade organic pollutants are N-type semiconductor materials, such as TiO₂, ZnO, CdS, WO, SnO₂, Fe₂O₃, etc.

    In recent years, as an effective method, photocatalytic technology has a good treatment effect on environmental pollutants. Among them, semiconductor heterogeneous photocatalysis has become the most eye-catching new technology because it can completely catalyze and degradate various organic and inorganic substances in polluted air and wastewater. This technology can completely degrade many organic pollutants into CO₂, H₂O, C1-, P043- and other inorganic substances, to reduce greatly the total organic content (TOC) of the system; many inorganic pollutants such as CN-, NOx, NH₃, H₂S, etc. can also be degraded through photocatalytic reactions.

    Among many semiconductor photocatalysts, titanium dioxide and nano cuprous oxide have always been at the core of photocatalysis research because of their strong oxidizing ability, high catalytic activity, and good stability. Many experts believe that Cu₂O has good application prospects in the photocatalytic degradation of organic pollutants, and it is expected to become a new generation of semiconductor photocatalysts after titanium dioxide. Cu₂O nano has relatively stable chemical properties and strong oxidizing ability under the action of sunlight, which can eventually completely oxidize organic pollutants in water to produce CO₂ and H₂O. Therefore, nano Cu₂O is more suitable for advanced treatment of various dye wastewater. Researchers have used nano Cu₂O photocatalytic degradation of methylene blue, etc., and achieved good results. 

    In recent years, cuprous oxide nanoparticles have been widely used in wastewater treatment and purification technologies. Compared with other traditional water treatment technologies, they have the advantages of complete high efficiency, low cost, stability and making use of sunlight, and have good and broad prospects. TiO₂ is commonly used to treat sewage by sunlight. However, this substance requires ultraviolet activation and has many drawbacks. Therefore, visible light as a light energy source for sewage treatment has always been the goal pursued by scientists.
