| 摘要 |
Metal nanoparticles sol with a metal particle content of = 1 g/liter, comprises silver nanoparticles, at least one dispersing auxiliary, at least one liquid dispersion medium, and at least one metal (0.1-10 wt.%, based on silver content of the metal nanoparticles sol) comprising ruthenium, rhodium, palladium, osmium, iridium or platinum, in the form of the metal or at least one metal compound. An independent claim is also included for producing the metal nanoparticle sol, comprising (a) combining silver salt solution, a solution containing at least one metal salt of ruthenium, rhodium, palladium, osmium, iridium or platinum and hydroxide ions containing solution, and (b) reacting the solution obtained from the step (a) with a reducing agent, where at least one of the solutions of step (a) contains at least one dispersing auxiliary, and the three solutions of the step (a) are combined simultaneously. |
