Reverse micelle synthesis

Poly(oxyethylene)nonylphenyl ether (Igepal-20) has been used in a combined synthesis of nanometer grains of silver on fine-grain silica (Li et al, 1999b). This method uses Igepal in a hexane solution with silver nitrate dissolved in the aqueous phase. Hydrazine hydrate is then added to reduce the Ag after the fine droplets of micelle have been formed, resulting in metallic silver particles contained inside the micelle. Then tetraethylorthosilicate

Electrostatic and steric stabilization are, in a sense, combined in the use of long-chain alkylammonium cations and surfactants, either in single-phase sols or in the reverse micelle synthesis of colloidal metals.

A scanty and inadequate record of synthesis is available in an article which may be the oldest record (1980) of reverse micelle synthesis of platinum particles [416]. The platinum particles, prepared by reduction of a Pt-salt, were reported to have a size of 3 nm with a very narrow size distribution.
