Abstract

The influence of the form of micelles and reactant concentrations on the formation and growth of gold nanoparticles in reverse micelles based on Triton X-100 (polyoxyethylene octyl phenyl ether) was studied. It was shown that spherical nanoparticles of 3–4 nm in size are formed in the presence of sodium sulfite and ascorbic acid and particles of an extended shape are formed in the presence of ascorbic acid alone. It was found that the ultimate shape and size of the nanoparticles depend not only upon the form of micelles but also on the acid concentration, since the products of its oxidation can be selectively sorbed on the surface of the particles and act as additional shape modifiers.
