Abstract:
1. A method for producing a metal-on-carrier, comprising causing nanocolloid metal particles to be carried on a carrier by use of a metal nanocolloidal liquid containing a dispersion medium and nanocolloidal metal particles, and containing substantially no protective colloid-forming agent, wherein the liquid has a nanocolloidal metal particle concentration of 250 mass ppm or more; wherein the protective colloid-forming agent content as reduced to carbon is equivalent to a total carbon of 0 to 200 mass ppm with respect to the nanocolloidal metal particles; wherein the dispersion medium is an aqueous medium, and the nanocolloidal metal particles are caused to be carried on the carrier through spraying; and, wherein the metal nanocolloidal liquid is concentrated in a vapor phase, and the nanocolloidal metal particles are caused to be carried on the carrier.
