Abstract

The chemically controlled polyol process, with TMAH and water as OH- donors in the nickel hydroxyglycolate intermediate phase, prepares the nickel nano particles. The water additive acts as the OH- donor and enhances the solubility of salt in polyol for efficient production and monodispersive particles. Water and TMAH, selected to decrease the contamination of alkali metal from inorganic base, as OH- donors control the intermediary solid phase as a reservoir for Ni2+ species. The particle is about 80 nm with a faceted shape when the reaction is controlled by a combination of TMAH and water,. The nucleating agent is powerful to decrease the particle size, but in this basic reaction condition, it is not effective enough to get a small size.
