Embodiment

[0039] A chiral manganese oxide nanoparticle and a preparation method thereof, the specific steps are as follows:

[0040] First configure 100mMMnCl 2 4H 2 O, 100mML- / D-tartaric acid solution and 50mg / mL sodium borohydride were dissolved, and then 100μL MnCl 2 4H 2 O, 200μL- / D-tartaric acid solution and 100μL sodium borohydride solution were added to 10mL pure water respectively, and then 1M NaOH solution was added drop by drop under stirring until the pH of the solution was about 10. After 10 hours of reaction, the solution was light brown and kept Stable, stop stirring.

[0041] Mix the reaction solution and isopropanol at a volume ratio of 1:4, centrifuge at 8000rpm for 10min after the solution becomes turbid, remove the supernatant, then dissolve the precipitate in ultrapure water, repeat washing twice to remove excess unreacted reactants to obtain The L- / D-manganese oxide nanoparticles.

Abstract

The invention relates to chiral manganese oxide nanoparticles as well as a preparation method and application thereof, and relates to the technical field of material chemistry. According to the chiral manganese oxide nano particle, a manganese precursor, tartaric acid and a reducing agent react under the alkaline condition to obtain the chiral manganese oxide nano particle; and the tartaric acid is L-tartaric acid or D-tartaric acid. The chiral manganese oxide nanoparticles have chiral optical activity at 300-900nm, the preparation method is simple, the application is wide, and the prepared manganese oxide nanoparticles have important significance in promoting the development of the fields of optics, life science, medicine and the like.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a chiral manganese oxide nanoparticle and a preparation method and application thereof. Background technique [0002] Chirality refers to an asymmetric configuration and is a natural property of molecules and biological systems. Organisms contain a large number of chiral structures, which affect asymmetric biochemical reactions with various physiological effects, and play a vital role in disease treatment and drug production. When the material shrinks to the nanoscale, that is, after the formation of nanomaterials, it has characteristics such as high specific surface area and electronic confinement, and exhibits unique properties in chemistry, catalysis, optics, electronics, and magnetism. Chiral nanostructures have a high similarity with biological macromolecules in terms of scale, composition and morphology. Therefore, inorganic chiral nanostructures can regulate t...
