Document Type and Number:
Japanese Patent JP2021066709
Kind Code:
A
Abstract:
To provide a method for producing nanoscale fine particles which can be used as a catalyst and the like.SOLUTION: Provided is a method for producing multi-element nanoparticles, comprising: a step of making a dendrimer of a concentration of 10 μM or more, having at least one selected from a phenylazomethine skeleton and a carbazole skeleton as a structural unit of a dendritic branch structure and many kinds of different metal salt compounds containing mutually different metal species exist in a solvent to generate integrated bodies in which the different metal salt compounds are integrated with the phenylazomethine-type dendrimer and accelerating coagulation of the integrated bodies; and a step of reducing the integrated bodies in the presence of a reducing agent.SELECTED DRAWING: Figure 3
