Abstract
nanoparticles approximately in diameter were electrochemically formed by liquid-phase reduction (i.e., electroless deposition) using hydrazine as a reducing agent and dispersing barely soluble particles in aqueous solution at . The addition of gelatin into the reaction suspension prevented the coagulation of nanoparticles and also sufficiently suppressed particle growth. Direct reduction of particles did not occur due to the adhesion of gelatin on the surface of particles, and nanoparticles were deposited by the reduction of ions dissolved in solution from particles. The solubility of particles was extremely small (of the order of at ) in aqueous solution of 12, which regulated the size of particles. nanoparticles approximately in diameter were obtained at , while nanoparticles of two different sizes (less than and about ) were obtained at . The proportion of the smaller particles increased with increasing reaction temperature, and the smaller particles were easily separated by centrifugal classification without aggregation. The formation mechanism of nanoparticles was discussed from the viewpoint of thermodynamics with in situ monitoring of deposition and immersion potential.
