Embodiment 1

[0040] Preparation of modified triazole-modified ferric oxide photocatalyst T1:

[0041] (1) Add 7.41 g of 2,3-dihydrobenzofuran-5-carbaldehyde, 9.98 g of ethyl nitroacetate, 1.95 g of sodium azide, and 150 mL of DMSO into a round-bottomed flask in sequence, stir evenly, and add 0.67 g g Aluminum trichloride, water bath at 70 °C and stirring, TLC monitoring the reaction, after the reaction is complete, add 80 mL of deionized water and 3 drops of concentrated hydrochloric acid to inhibit AlCl 3 was hydrolyzed, extracted three times with 50 mL of ethyl acetate, and the organic layers were combined, washed with saturated sodium chloride, dried over anhydrous sodium sulfate, removed under reduced pressure for ethyl acetate, and purified by column drying to obtain solid A2.

[0042] (2) 10.74 g of A2 solid and 50 mL of acetonitrile were sequentially added to the three-necked flask and stirred, 5.80 g (0.042 mol) of potassium carbonate was added, and 5.72 g of bromoethane (R) was ...

Embodiment 2

[0052] Preparation of modified triazole-modified ferric oxide photocatalyst T2:

Abstract

The invention provides a triazole modified ferric oxide photocatalyst and a preparation method thereof, and belongs to the technical field of environmental governance, the triazole modified ferric oxide photocatalyst is obtained by modifying ferric oxide with a triazole compound; in addition, photocatalytic activity screening of the triazole modified ferric oxide photocatalyst is also carried out, and research on the relationship between the illumination time of the triazole modified ferric oxide photocatalyst and the degradation rate of methyl orange is carried out at the same time. The triazole modified ferric oxide photocatalyst prepared by the invention has very high light utilization rate, photocatalytic activity and organic matter oxidative degradation capability, and can be used for oxidative degradation of organic pollutants in the technical field of environmental governance.

Description

technical field [0001] The invention relates to a triazole-modified ferric oxide photocatalyst and a preparation method thereof, and belongs to the technical field of environmental treatment. Background technique [0002] The wastewater produced by printing and dyeing factories processing cotton, hemp, fiber and their blended products is called printing and dyeing wastewater. The printing and dyeing wastewater not only has a high concentration of organic matter, but also has a large chromaticity. Because the printing and dyeing industry is a water-consuming industry, so the printing and dyeing wastewater It also has the characteristics of huge emissions. Printing and dyeing wastewater not only pollutes the water environment, but also destroys the ecological balance of the water body, threatening the survival of aquatic organisms, and also affects the safety of human drinking water sources, becoming a difficult or hot spot in environmental governance. Photocatalytic oxidatio...
