Application method of metal oxide and metal organic framework composite material in photocatalytic degradation of antibiotics

Abstract

The invention relates to an application method of a metal oxide and metal organic framework composite material in photocatalytic degradation of antibiotics, and belongs to the field of composite material synthesis and environmental governance. The application method of the metal oxide and metal organic framework composite material in photocatalytic degradation of antibiotics comprises the following steps: firstly, preparing a petal-shaped metal oxide precursor, and then preparing the metal organic framework material on the metal oxide in situ through chemical reaction. The method has the advantages of being green, free of pollution, efficient, low in energy consumption, wide in application range and the like when being used for treating the antibiotics in the water environment through a photocatalysis technology, is used for efficiently degrading the antibiotics in wastewater of sewage treatment plants and agriculture and animal husbandry, and is beneficial for treating the environment; meanwhile, due to the porous characteristic and the high specific surface area characteristic of the metal organic framework material, the problem that a semiconductor catalyst cannot enrich a substrate is solved, so that antibiotics in the environment can be adsorbed and enriched, and the photocatalytic degradation efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of composite material synthesis and environmental treatment, in particular to an application method of metal oxide and metal organic framework composite materials in photocatalytic degradation of antibiotics. Background technique [0002] With the deepening of industrialization and the acceleration of urbanization, a large amount of industrial wastewater and urban wastewater contain a large amount of pollutants such as heavy metal ions, dyes and drugs. As the most widely used drug, antibiotics exist in large quantities in the water environment due to their excessive use. The enrichment of antibiotics in the water has biological toxicity to the microorganisms in the water environment, thus destroying the ecological environment of the water body and making it gradually deteriorated. At the same time, the long-term Being in an antibiotic environment will lead to the emergence of drug-resistant genes, resulting ...
