Problems solved by technology

Most traditional catalysts not only have low catalytic efficiency, but also their preparation is based on experience, which not only causes a huge waste of production raw materials, makes it difficult to improve economic benefits, but also causes pollution to the environment
For large-scale industrial synthetic reactions, it can be a big burden every year

Embodiment 1

[0033] Take 5.52mL of 0.25mmol / L aqueous solution and 0g of PEG600 prepared by zinc acetate with a mass of 0.300g, and place them in a 20mL polytetrafluoroethylene reaction kettle, stir magnetically for 30min at room temperature, and dry at a constant temperature React in the box at 90°C for 24 hours, and after the reaction, the reaction kettle is left to cool naturally. The obtained cuttlebone was repeatedly washed with distilled water and ethanol three times to remove the residue on the surface of the cuttlebone, and finally placed in a constant temperature drying oven at 80°C for 4 h to obtain ZnO nanoflowers loaded in three-dimensional channels. The product was observed with a scanning electron microscope (SEM), see Figure 1 for reference.

[0034] Wherein, the preparation method of the cuttlebone includes: selecting commercially available dried cuttlefish with a weight of 850-1025 g, taking out the sampan-shaped cuttlebone from the dried cuttlefish and removing the shell,...

React in a drying oven at 100°C for 24 hours. After the reaction, the reaction kettle is left to cool naturally. The obtained cuttlebone was repeatedly washed with distilled water and ethanol three times to remove the residue on the surface of the cuttlebone, and finally placed in a constant temperature drying oven at 80°C for 4 hours to obtain ZnO nanoflowers loaded in three-dimensional channels. The product was observed with a scanning electron microscope (SEM).

Embodiment 3

[0038] Take 5.52mL of 0.25mmol / L aqueous solution and 1.800g of PEG600 prepared by zinc acetate with a mass of 0.300g and place them in a 20mL polytetrafluoroethylene reactor. React in a drying oven at 90°C for 12h, then adjust the temperature to 100°C and continue to react for 24h. After the reaction, the reaction kettle is left to cool naturally. The obtained cuttlebone was repeatedly washed with distilled water and ethanol three times to remove the residue on the surface of the cuttlebone, and finally placed in a constant temperature drying oven at 80°C for 4 h to obtain ZnO nanoflowers loaded in three-dimensional channels. The product was observed with a scanning electron microscope (SEM).

Abstract

The invention discloses a preparation method of a ZnO nano flower loaded in a three-dimensional duct. The preparation method comprises the following steps: adding a certain amount of zinc salt solution and a dispersion agent PEG600 into a reaction kettle of Teflon, putting the prepared porous cuttlefish bone, sealing the reaction kettle, standing the reaction kettle after reaction, repeatedly washing the obtained catalyst cuttlefish bone by ethyl alcohol and distilled water, and drying so as to obtain the corresponding ZnO nano flower loaded cuttlefish bone photocatalyst. The catalysis effect of the cuttlefish bone photocatalyst is researched. The preparation method provided by the invention is used for successfully preparing the ZnO nano flower loaded in the cuttlefish bone, and the ZnO nano flower has excellent physical and chemical properties; the catalysis experiment proves that the ZnO nano flower loaded cuttlefish bone as a catalyst has excellent photocatalysis activity, and has a wide application prospect in the catalysis field. In the whole preparation process, the operation is simple; the raw material cost is low; the equipment investment is low, and the ZnO nano flower loaded in the three-dimensional duct is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of catalysis of metal oxide semiconductor nanomaterials, and in particular relates to a method for preparing semiconductor metal oxide nanoflowers loaded in three-dimensional channels for photocatalytic degradation of methylene blue. Background technique [0002] Research on semiconductor nano-optical materials is becoming more and more extensive. Fujishima and Honda utilize TiO from 1972 2 The electrode experiment found that the phenomenon of photolysis of water began, and people gradually began to study semiconductor materials. As a new type of material, nanomaterials have only been developed for 20 or 30 years. In recent years, my country has carried out in-depth research on nanotechnology in the fields of energy, environment, resources, and sewage treatment by combining national strategic needs. Subsequently, photocatalytic properties have been widely studied as an optical property of nanomaterials. It refers t...
