Abstract:
The present invention provides a method for reducing metal ions (for example, silver ions) and stably dispersing metal nanoparticles by nanosilicate platelets. An organic dispersant, nanosilicate platelets and a metal ionic solution are mixed to perform a reductive reaction, wherein the organic dispersant is tri-sodium citrate dihydrate (SCD), chitosan or polyvinyl pyrrolidone (PVP), to produce a mixture of stably dispersed metal nanoparticles.
