Problems solved by technology

However, these nanomaterials mimic enzymes still have some defects, for example, a single Fe 3 0 4 The peroxidase activity of magnetic nanoparticles is much lower than that of horseradish peroxidase, and FeS nanoparticles are not stable and susceptible to air oxidation, which leads to changes in their catalytic activity. These factors greatly limit the size of nanomimetic enzymes. Scale practical application and promotion

Abstract

The invention discloses a hollow copper sulfide / polypyrrole nanocomposite, which has similar peroxidase activity and can generate strong oxidizing hydroxyl radicals by catalyzing H2O2, and can be applied to the detection and analysis of glucose content in food and blood Or the oxidative degradation of organic pollutants in sewage. The nanocomposite of the present invention combines the advantages of copper sulfide and polypyrrole nanomaterials. After compounding, the synergistic catalytic effect of the hollow copper sulfide / polypyrrole nanocomposite is obviously better than that of single copper sulfide particles or polypyrrole particles, and has catalytic High efficiency, short color development time, less usage, stable chemical activity, wide application range, etc., can be used as a substitute for natural peroxidase, used in the detection of glucose content in food and organisms, and in the detection of organic Oxidative degradation of dyes.

Description

Technical field [0001] The present invention is a nanomaterial technology field, and it involves a hollow copper sulfide / polypyrum nano composite and its application with similar peroxidase activity. Background technique [0002] Since Yan Xiyun's research team discovered Fe 3 0 4 Since nanoparticles have similar characteristics of oxidase, nanoparticles have received widespread research on research as peroxide simulation enzymes. Since then, many different types of nanoparticles such as AU, PT, CEO 2 , FES, Cuo, CUS nano -slices, carbon quantum dots, carbon -based carbon nanotubes, etc., are constantly found to have peroxide simulation enzyme activity.Compared with natural enzymes, nano -particle peroxide simulation enzymes have the advantages of high stability, simple preparation, and high catalytic activity, and have a wide range of application prospects in biological analysis and wastewater management.However, there are still some defects in these nano -material simulation en...
