机译:尺寸和形态可控的胶态贵金属纳米粒子的合成

摘要

The present invention relates to colloidal dispersions comprising a plurality of precious group nanoparticles, wherein about 90% or more of the precious group metal is in fully reduced form; a dispersion medium comprising a polar solvent; a water-soluble polymer suspension stabilizing agent; and a reducing agent, wherein the nanoparticle concentration is at least about 2 wt. % of the colloidal dispersion, wherein the nanoparticles have an average particle size of about 1 to about 6 nm and at least 95% of the nanoparticles have a particle size within this range; and further wherein the colloidal dispersion is substantially free of halides, alkali metals, alkaline earth metals and sulfur compounds. Methods of preparing, further processing, and using such colloidal dispersions are also provided herein.
