[0021] (1) Ce(IO 3 ) 4 preparation of

[0022] 1 mmol ammonium cerium nitrate ((NH 4 ) 2 Ce(NO 3 ) 6 ) 40 mL deionized water to obtain cerium ammonium nitrate solution. 4 mmol of sodium iodate (NaIO 3 ) was dissolved in 40 mL deionized water to obtain a sodium iodate solution. While stirring the sodium iodate solution, ceric ammonium nitrate was added dropwise to the sodium iodate solution at room temperature. After the dropwise addition was completed, stirring was continued for 1 h. The obtained precipitate was washed twice with deionized water (50 mL of deionized water each time), and after centrifugation, it was dried in an oven at 60 °C for 12 h to obtain Ce(IO 3 ) 4 sample.

Abstract

The invention discloses an application of Ce(IO3)4, and provides an application example of the compound for the first time. As a catalyst, the Ce(IO3)4 can degrade organic dyestuff pollutants under a condition of completely lucifugal room temperature. The Ce(IO3)4 catalyzes and degrades the activity of Rhodamine B (RhB) and methyl orange (MO) dyestuff under a completely lucifugal condition, and is apparently superior to a commercial titanium dioxide (P25) photocatalyst under visible light irradiation. When the Ce(IO3)4 disclosed by the invention catalyzes and degrades dyestuff, illumination is not required; the activity is relatively high; the preparation method for the Ce(IO3)4 is simple; the preparation condition is mild; therefore, the Ce(IO3)4 is favorably popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control and relates to Ce(IO 3 ) 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 th...
