Background
With the rise of printing and dyeing and textile industry, the environmental problems caused by organic dye wastewater are becoming more serious, and the treatment of organic dye wastewater becomes the central importance of sewage treatment. The organic dye wastewater has high chromaticity, is toxic and is not easy to be biochemically degraded, and the current common methods for treating the wastewater comprise an adsorption method, a chemical oxidation method, a biological method and the like, but the methods can not efficiently remove organic pollutants in the dye wastewater. Therefore, the research and development of the treatment technology and the method for efficiently treating the organic dye wastewater have important theoretical and practical significance.
In the face of these problems, many scientists thought to utilize photocatalytic oxidation technology to treat organic matter in dye wastewater and achieved considerable results. Of which the nanometer TiO is widely concerned by the big families2But TiO 22There are also problems with application in the field of photocatalytic oxidation. First, TiO2The forbidden band width of the light absorption material is 3.2eV, the light absorption material can only absorb about 4% of ultraviolet light in sunlight, and the utilization rate of visible light is low. Second, photo-excited TiO2Easily generate electron-hole pairs, and generate electrons to TiO by light2In the process of surface migration, electrons and holes can be in TiO2Internal or surface recombination of (2) resulting in a reduction of TiO2The efficiency of the light quanta of (c). Finally, by means of TiO2When the organic dye wastewater is degraded, the problems of easy agglomeration, difficult recovery and the like exist. Therefore, researchers have searched for photocatalysts having a relatively narrow forbidden band width and capable of utilizing sunlight sufficiently to solve the above-mentioned problems.
CuO and Cu2O is a p-type semiconductor havingHigh photocatalytic activity, low cost, stable chemical property, etc. CuO and Cu2The forbidden band width of O is 1.2eV and 2.0eV respectively, and the carrier can be generated under visible light, thereby not only overcoming the defect that TiO2The defect of low utilization rate of visible light can be overcome, and CuO can be used for TiO2Modified to reduce TiO2Probability of photo-generated electron-hole recombination. These advantages result in CuO and Cu2The O has good application prospect in the field of treating organic dye wastewater. However, the use of CuO and Cu is under way2In the process of carrying out photocatalytic oxidation treatment on organic dye wastewater by O, the problems of easy agglomeration, difficult recovery and the like also exist. To solve these problems, scientists have studied supported CuO and Cu2O, thereby obtaining the photocatalytic composite material with larger specific surface area and better photocatalytic effect, and being beneficial to recycling.
Bentonite is a 2:1 type crystal structure of layered silicate mineral composed of two layers of silicon-oxygen tetrahedron and one layer of aluminum-oxygen octahedron, and has the characteristics of large specific surface area, good adsorption performance, strong ion exchange, stable property, low price, large reserve capacity and the like, and is one of the best choices of carriers. By utilizing the structural characteristics of the expanded soil, photocatalyst particles are introduced on the surface and in the interlayer space of the expanded soil, and the supported photocatalyst can be prepared. It is reported that bentonite can react with ZnO, Ag3PO4、Au-TiO2And the composite photocatalyst is prepared by combining the steps of the preparation method and the application, and is used for treating the dye pollutants.
