Problems solved by technology

If the light intensity is very weak, or there is no light, the catalytic activity cannot be shown, which limits the application of the catalyst
[0005] Cerium-containing compounds such as ceria (CeO 2 ) is an important class of catalysts that can be used to eliminate or degrade pollutants. In addition, it is also widely used in photocatalysts, fuel cells, solar cells and other fields. However, the catalytic activity of ceria is not high
CaO 4 is a CeO 2 and GeO 2 Composed of inorganic composites, its preparation method and application research as a photocatalyst have long been documented ( Angewandte Chemie International Edition , 2012, 51, 3611-3615; Journal of Solid State Chemistry , 2013, 197, 204-208), but there are no patents and literature reports on CeGeO 4 Study on Degradation of Organic Dyes as Catalysts in the Absence of Light

Embodiment 1

[0021] (1) CeGeO 4 preparation of

[0022] 2 mmol of Ce(NO 3 ) 3 , 2 mmol of GeO 2 Dissolve in 50 mL deionized water, add a small amount of NaOH to adjust the pH of the solution to 10. After stirring at room temperature for 30 min, the solution was transferred to a 70 mL hydrothermal reactor. The reactor was placed at 200 °C for 24 h. Then take out the reactor and let it dry naturally at room temperature. Then the precipitate in the reaction kettle is separated and dried at room temperature to obtain CeGeO 4 sample.

[0023] (2) CeGeO 4 representation of

[0024] from figure 1 Visible, CeGeO 4 The crystal phase of the sample and CeGeO in JCPDS No. 40-1182 in "Powder Diffraction Card Collection" 4 The standard crystal phases are completely consistent, indicating that CeGeO 4 Sample prepared successfully.

Abstract

The invention discloses an application of CeGeO4. CeGeO4 as a catalyst has catalytic activity under an illumination condition and also can degrade organic dye pollutants under a completely lucifugal room temperature condition, and an application scope of CeGeO4 is enlarged. CeGeO4 ha apparently higher activity of catalytic degradation of rhodamine B (RhB) and methylene blue (MB) dyes under the completely lucifugal condition as compared with a CeO2 catalyst. CeGeO4 does not require illumination and has higher activity during catalytic degradation of the dyes; a preparation method of CeGeO4 is simple; a preparation condition is mild; and the popularization and application of CeGeO4 is facilitated.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control and relates to CeGeO 4 Application of the compound as a novel catalyst in the degradation of organic dye pollutants. Background technique [0002] With the increase of population, the scale of the printing and dyeing industry in the world is constantly expanding. The large amount of organic dye pollutants discharged by this industry has become an important source of water pollution in the world. Semiconductor photocatalysis technology can directly use sunlight to efficiently oxidize and degrade dye pollutants at room temperature. Therefore, it is a favorable way to control environmental pollution by making full use of sunlight to degrade dye pollutants through photocatalytic technology. Because ultraviolet light only accounts for about 4% of the total energy of sunlight, while visible light accounts for about 46%, so the key to utilizing solar energy is to utilize the vis...
