Abstract

The invention discloses a preparation method of chiral nanometer copper oxide with optical activity. The preparation method comprises the following steps of: (1) dissolving an achiral anionic surface-active agent and a chiral small molecule into water at room temperature to obtain an achiral anionic surface-active agent and chiral small molecule water solution; (2) adding inorganic copper salt to the achiral anionic surface-active agent and chiral small molecule water solution, and stirring to react for 10-60 minutes; (3) adding alkali to reaction liquid obtained from the step (2), then increasing temperature to 100-200 DEG C, and reacting for 30 minutes-6 hours; (4) after the reaction is finished, centrifugalizing or filtering the reaction liquid obtained from the step (3), and washing and drying to obtain the chiral nanometer copper oxide with the optical activity. The prepared chiral nanometer copper oxide with the optical activity shows very uniform flower-shaped appearance and shows outstanding optical activity by having chirality.

Description

technical field [0001] The invention relates to a preparation method of an inorganic chiral material, in particular to a preparation method of optically active chiral nano-copper oxide. Background technique [0002] Copper oxide is a narrow bandgap P-type semiconductor material. As a common and important multifunctional inorganic material, it has been widely used in production and life for decades, such as: magnetic materials, light absorption, sensors, superconductivity Materials, catalysts and biomedicine and other fields. At present, copper oxide nanoparticles with various shapes have been synthesized by various methods, such as nanowires, nanorods, nanobelts, nanotubes, and microspheres. Recently, Chinese patents (publication numbers [CN103241761A] and [CN103272599A]) disclose two methods for preparing flower-shaped nano-copper oxide particles. But none of these nanoparticles have chiral properties. [0003] Chiral inorganic nanomaterials exhibit special electrical, o...
