Gold hydroxo anion complex solution and method for producing gold nanoparticle carrier

摘要

The present invention relates to a trigonal gold hydroxo anion complex having a planar tetragonal structure in which at least one ligand is OH- and does not contain a halogen anion as a ligand, and a weak acid not coordinated to gold. After impregnating the carrier with a gold hydroxo anion complex solution consisting of a transparent solution having a conjugate base and no halogen anion and having a pH of 8 or more, water is removed, and then heat treatment is performed, followed by washing with water. A method for producing a gold nanoparticle carrier characterized by the above is provided. According to the method of the present invention, in a method for preparing a gold nanoparticle catalyst using a liquid phase method, a gold compound containing no halogen such as chlorine can be used efficiently as a raw material, and this can be efficiently supported, and simple preparation Depending on the method, a highly active gold nanoparticle-supported catalyst can be obtained.
