Abstract

The invention provides a synthetic method for chiral copper oxide nanoparticles, belonging to the technical field of synthetic chemistry. According to the invention, a reducing agent and chiral molecules act on a copper oxide precursor under a non-hydrothermal mild condition so as to form a monodisperse nano-sized copper oxide particle. The synthetic method comprises the following main steps: thesynthesis of the copper oxide precursor; and the synthesis of chiral copper oxide nanoparticles with different ligands. The synthetic method of the invention solves problems in the synthesis of chiralcopper oxide nanoparticles under non-organic-phase and non-hydrothermal conditions, and develops the synthetic technology for nano-scale chiral copper oxide nanoparticles with regular morphology. Inaddition, the synthesized chiral copper oxide nanoparticles are very stable and have broad biological application prospects.

Description

technical field [0001] The invention relates to a method for synthesizing chiral copper oxide nanoparticles, which belongs to the technical field of synthetic chemistry. Background technique [0002] Chirality comes from the inability of matter and its mirror image to overlap, which is a basic attribute of nature. The living body is also a chiral environment. The basic unit of amino acids in proteins in living bodies is D-type. Therefore, the study of chiral substances is of great significance to living bodies. . As we all know, metal oxides play an important role in the field of catalysis, especially transition metal oxides, which are more and more widely used in solar cells, electrocatalysis and other fields. Therefore, it is very meaningful to study chiral transition metal oxides to develop a kind of chiral catalysis in vivo. The synthesis method of nanoscale chiral copper oxide nanoparticles has not been reported yet. Contents of the invention [0003] The purpose o...
