AbstractSilver nanoparticles were synthesized in sodium bis(2-ethylhexyl)-sulfosuccinate (AOT) reverse micelles in isooctane with tetraethylene glycol dodecyl ether (C12E4) as a cosurfactant. Recovery of the Ag particles from the reverse micelles by dissolving antisolvent CO2 in the micellar solution was investigated. All the Ag particles in the reverse micelles could be precipitated by compressed CO2 at suitable pressures, while the surfactants remained in the isooctane continuous phase, and well-dispersed Ag nanoparticles were obtained. The effects of operating conditions on the size and size distribution of the Ag particles were investigated. The particle size decreased with decreasing molar ratio (w) of water to surfactant. A higher CO2 pressure in the recovery process favored production of smaller particles. A decrease in the molar ratio of reductant KBH4 to AgNO3 resulted in larger Ag particles with higher polydispersity.
