Problems solved by technology

However, the single BiOCl photocatalyst has disadvantages such as too high bandgap width and low quantum efficiency, resulting in low photocatalytic activity of BiOCl photocatalysts.
Moreover, the application of nano-sized BiOCl photocatalysts in sewage treatment has problems such as difficult solid-liquid separation and low catalyst recycling efficiency, which makes the actual application cost too high, and there are certain difficulties and distances in the real application.

Abstract

Belonging to the technical field of photocatalysis, the invention discloses a preparation method and application of a visible light responsive yttrium-doped bismuth oxychloride catalyst. The preparation method of the visible light responsive yttrium-doped bismuth oxychloride catalyst includes: step 1: mixing bismuth nitrate pentahydrate with yttrium nitrate hexahydrate evenly and performing dissolving in an ethylene glycol monomethyl ether solution to obtain a solution I; step 2: dissolving 1-hexadecyl-3-methylimidazolium chloride in an ethylene glycol monomethyl ether solution for complete dissolution to obtain a solution II; step 3: pouring the solution II slowly into the solution I, and carrying out reaction in a reaction kettle; and step 4: carrying out centrifuging, washing and dryingtreatment on the reacted solution obtained in step 3, thus obtaining the yttrium-doped bismuth oxychloride catalyst. The yttrium-doped bismuth oxychloride catalyst prepared by the method provided bythe invention has the characteristics of high catalyst recycling efficiency, low cost and high efficiency treatment of antibiotic wastewater.

Description

technical field [0001] The invention relates to the technical field of photocatalysis, in particular to a preparation method and application of a visible light-responsive yttrium-doped bismuth oxychloride catalyst. Background technique [0002] In recent years, due to the advantages of antibacterial and growth promotion, antibiotics have been widely used in medical and other industries and accompanied by a large amount of abuse. As a result, excess antibiotic substances are continuously discharged into the aquatic environment. Due to the continuous discharge behavior, although the half-life of antibiotics is not long, it still causes residue and accumulation in water bodies and sediments, eventually leading to environmental and ecological damage. Antibiotics are also called pseudo-persistent organic compounds. Tetracycline antibiotics have good water solubility, and mainly enter the natural environment such as surface water and groundwater through surface runoff. Although ...
