The conditions of the reduction synthesis of metallic rhodium nanoparticles, intended for catalysis of electrochemical reactions, proceeding on cathodes was investigated by the method hydrosol in water solution of TW-20 dispersity stabilizer in presence black-carbon XC-72 and without it. The formation in resulting colloidal system of monodispersed rhodium particles with average size not more than 50 nm and their stability was confirmed by the method of dynamic light scattering.
