METHOD OF CREATING NANOPARTICLE AND ELECTROLESS PLATING USING IRRADIATION OF SYNCHROTRON X-RAY

摘要

The present invention relates to methods for nanoparticle production and electroless plating, which comprise immersing an object in an aqueous solution containing a metal salt and a reducing agent, and irradiating the aqueous solution with X-ray. The X-ray is high-transmission X-ray, such as synchrotron X-ray. As a result, the nanoparticles can be produced and the formation of an electroless plating film on the object surface can be effectively achieved. The object may be catalytic or non-catalytic at least at its surface. The electroless plating method of the present invention allows plating of the object at room temperature without a separate activation process, even if the object is non-catalytic.
