Abstract
Finely divided crystalline palladium has been synthesized from several inorganic precursors by chemical reduction in ethylene glycol. Pallad ium black is produced when ethylene glycol serves as solvent and reduc ing agent. Monodisperse spherical particles are produced by the hydraz ine reduction of [Pd(NH3)4]2+ in ethylene glycol in the temperature ra nge from 20-degrees-C to -9-degrees-C. Control of particle size, shape and degree of dispersion is achieved by making changes in the reactio n parameters, which in turn affect the reduction, nucleation and growt h steps.
