Background
In the 21 st century, human beings have faced two very serious problems of energy and environment, especially the environmental problem caused by toxic and non-degradable organic pollutants (such as polycyclic aromatic hydrocarbon, polychlorinated biphenyl, pesticide, dye, etc.), which has become a significant problem affecting human survival and health. Organic pollutants can be effectively oxidized and decomposed by utilizing the characteristic that the surface of the semiconductor oxide material can be activated under the irradiation of sunlight. Compared with the traditional environment purification treatment method, the semiconductor photocatalysis technology has the advantages of mild reaction conditions, no secondary pollution and operationSimple preparation, obvious degradation effect and the like. The most studied and used photocatalyst since the development of photocatalytic technology was TiO2. However, the generated photogenerated electron-hole pairs are easy to recombine, so that electrons and holes cannot be timely transferred to the surface to participate in redox reaction, and the light conversion efficiency is low. Therefore, it is important to prepare a photocatalyst having high activity. Because copper is a nontoxic cheap metal, compounds containing toxic elements such as lead, antimony, cadmium, mercury and the like, such as CuO, Cu, are increasingly substituted for the preparation of photocatalysts in recent years2O, and the like. In recent years, TiO2The nanosheets have attracted extensive attention due to their unique platelet morphology. However, the separation efficiency of the electron-hole pairs is still not high, and therefore, the method is a very effective means for improving the separation efficiency of the electron-hole pairs by combining with a metal material capable of promoting the directional flow of electrons. In the existing report, Junhua et al reported that elemental copper is epitaxially grown on TiO2The {101} crystal face (application publication No. CN 104722300A); wang Yanfen et al reported a Cu2O/TiO2Composite photocatalytic material (application publication No. CN 106466604A).

Detailed Description
The present invention will be described in detail with reference to specific examples.
The first embodiment is as follows:
adding 5.35g of wt40% hydrofluoric acid and 1.2g of water into 30g of glacial acetic acid in a beaker, stirring for 30 minutes, adding 1.71g of tetrabutyl titanate, stirring for 0.5 hour, transferring into a polytetrafluoroethylene lining, and carrying out hydrothermal reaction at the constant temperature of 180 ℃ for 24 hours; washing, centrifuging, drying, calcining at 600 ℃ for 2 hours to obtain the pure-phase TiO2And is in the form of sheet.
Then 0.16mmol of copper sulfate pentahydrate and 0.1g of pure phase titanium dioxide are added into 30mL of ethylene glycol in a flaky manner and stirred for 10 minutes;
then adding 0.32mmol of ascorbic acid into the solution, and stirring for 30 minutes; then, the mixture is added into a polytetrafluoroethylene lining autoclave, hydrothermal reaction is carried out for 2.5 hours at the constant temperature of 80 ℃, centrifugation, washing and drying are carried out, and Cu-TiO is obtained2。
For Cu-TiO2The composite photocatalyst is analyzed, and then,
deposition amount of Cu and TiO2Is 0.1: 1.
as can be seen from FIG. 1, the Cu-TiO prepared by the invention2The composite photocatalyst is in a sheet shape,the side length of the sheet is 0.5-2 microns, and the thickness is 30-100 nanometers.

Effect example two:
the test procedure was as follows:
Cu-TiO prepared in example one2Composite photocatalyst and pure-phase TiO2Respectively degrading waste water solution containing RhB.
Weighing Cu-TiO respectively20.05g of composite photocatalyst, pure phase TiO20.05g of the dye is respectively added into 200ml of RhB aqueous solution, wherein the concentration of the RhB is 12.5mg/L, and the mixture is stirred for 30min in a dark place, so that the dye is adsorbed/desorbed on the surface of the catalyst to be balanced. Then starting a xenon lamp light source to perform a photocatalytic reaction under the irradiation of ultraviolet light, and detecting the supernatant by using a spectrophotometer. According to the Lambert-Beer law, the concentration change of the organic matter can be quantitatively calculated according to the change of the characteristic absorption peak intensity of the organic matter. When the light-absorbing substances are the same and the thicknesses are the same, the change in the concentration of the solution can be directly expressed by the change in absorbance. Because RhB has a characteristic absorption peak at 554 nm, the change of the absorbance can be used for measuring the change of the concentration of RhB in the solution.
