Preparation of Metal Nanoparticles by Chemical Reduction

Among the conventional processes of nanoparticle preparation, chemical reduction of precursor ions by organic acids can be the most popular process. Other preparation processes of nanoparticles by chemical reduction are described in detail [Pg.190]

PVP (poly(7V-vinyl-2-pyrrolidone))-stabilized metal nanoparticles can be readily produced by alcohol reduction of the corresponding metal ions [5,32-34]. Alcohol can be a good reducing reagent of precious metal ions and it changes to aldehyde or ketone by oxidation (Fig. 6.6). This alcohol reduction is mild and easy. PVP-stabilized nanoparticles of platinum group metals can work as effective catalysts. Especially, various alloy nanoparticles can be obtained by this process, especially. [Pg.193]
