Metal nanoparticle composite body, metal colloidal solution, and methods for producing these
Provided are metal nanoparticle composite body whose multiple properties, such as a good metal nanoparticle control property, high dispersion stability, a good low-temperature firing property, and ease of purifying and separating metal nanoparticles, are intentionally added and controlled so that practical electrical conductivity can be exhibited, a metal colloidal solution in which the metal nanoparticle composite body is dispersed, and methods for producing these. A metal nanoparticle composite body includes a nitrogen-containing compound (A) and a metal nanoparticle (B), in which the nitrogen-containing compound (A) contains an oxidized nitrogen atom. A metal colloidal solution is obtained by dispersing the metal nanoparticle composite body in a medium. A method for producing a metal colloidal solution is characterized in that metal ions are reduced in a medium in the presence of a nitrogen-containing compound (A) containing an oxidized nitrogen atom so as to form metal nanoparticles (B).
