Title:
METHOD FOR PRODUCING GOLD NANOPARTICLE-CARRYING POWDER
Document Type and Number:
Japanese Patent JP2020037537
Kind Code:
A
Abstract:
To efficiently produce a gold nanoparticle-carrying powder that has only a minimum amount of an additive such as a dispersant, and is free of impurities.SOLUTION: The present invention provides a method for producing gold nanoparticle-carrying powder that is obtained by: adding a base powder for carrying gold nanoparticles thereon, to a mixture solution having an ammonia solution added to a solution containing gold ions; disposing at least two electrodes in a gas above the liquid level of the mixture solution; applying voltage to between electrodes in a rare gas atmosphere; and generating plasma between the electrodes and the liquid level. There is also provided a gold nanoparticle-carrying powder thereof.SELECTED DRAWING: Figure 1
