Abstract

Platinum and palladium powders with average particle sizes in the submicron range have been synthesized at room temperature by hydrazine reduction of \({\text{PtC}}{{\text{l}}_{\text{6}}}^{{\text{2 - }}}\) and \({\text{Pd(N}}{{\text{H}}_3})_4^{2 + }\), respectively, in glycols. Platinum powders contain spherical particles with a bimodal size distribution. Palladium powders also contain spherical particles, but the size distribution is narrow. The effect of both ammonia and hydrazine concentration on the size distribution and average size of palladium particles was investigated.
