Title:
HOLLOW METAL NANOPARTICLE, CATALYST INCLUDING SAME, AND METHOD FOR MANUFACTURING HOLLOW METAL NANOPARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/047906
Kind Code:
A1
Abstract:
The present specification relates to a method for manufacturing a hollow metal nanoparticle and a hollow metal nanoparticle manufactured by the method, the method comprising the steps of: 1) preparing a composition comprising two or more types of metal salts, one or more types of ionic surfactants, a surface stabilizer, and a solvent in an air atmosphere; and 2) adding a reductant into the composition in an air atmosphere. Additionally, the present invention relates to a hollow metal nanoparticle and a catalyst including the hollow metal nanoparticle, the hollow metal nanoparticle comprising: a hollow core portion; a shell portion including a first metal and a second metal; and a hollow space formed from the outer surface of the shell portion to the hollow core, wherein the ratio between the content of the first metal and the content of the second metal in the shell portion is larger than or equal to 1:3 and is smaller than or equal to 1:20.
