Title:
LIQUID DISPERSION OF PROTEIN TEMPLATE, METHOD FOR PRODUCING LIQUID DISPERSION OF PROTEIN TEMPLATE, AND METHOD FOR PRODUCING ALLOY NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2020/230295
Kind Code:
A1
Abstract:
A liquid dispersion of a protein template according to the present embodiment comprises a protein template in which at least two types of heterogeneous metal ions or alloy nanoparticles are encapsulated and a solvent in which the protein template is dispersed, and the alloy nanoparticles are obtained by removing the protein template. A method for producing a liquid dispersion of a protein template according to the present embodiment comprises the steps of: adding a protein template to a solution having heterogeneous metal ions dissolved therein to introduce the metal ions into the protein template; and separating between the protein template and metal ions that are not incorporated in the protein template. A method for producing alloy nanoparticles according to the present embodiment comprises the step of subjecting a liquid dispersion of a protein template having heterogeneous metal ions encapsulated therein to a heat treatment under a reducing atmosphere to remove the protein template. A method for producing alloy nanoparticles according to the present embodiment comprises the step of subjecting a liquid dispersion of a protein template having alloy nanoparticles encapsulated therein to a heat treatment, an ultraviolet ray treatment, a radioactive ray treatment or a plasma treatment to remove the protein template.
