Photochemical Method of Controlling Dispersity of Nanostructures of Transition Metals

摘要

Original methods of photochemical preparation of stable mono- (Cu, Ag, Au, Ni, Pd, Pt) and bimetallic nanoparticles in the form of optically transprent compact films on quartz surface and of volume dispersions in porous inorganic (silica glasses) and organic (MF-4SK fluorocarbon) materials, solid polymers (polyvinyl alcohol, polyethylene glycol, gelatin, latexes), and in liquid media (glycerol) are reviewed. The results of studies of spectral and structural characteristics of nanophase films under various experimental conditions are presented. Experimental mechanistic models and ways of controlling disperse composition of metal colloids, which can be used for photochemical synthesis of nanophase systems, are proposed.
