Controlled growth of microporous crystals nucleated in reverse micelles

Controlled Growth of Gold Nanoparticles in AOT/C12E4/Isooctane Mixed Reverse Micelles

“…Many monodispersed metal particles have been obtained in reverse micellar system, but most of their shapes have been limited to spheres. Recently, the shapecontrolled growth of copper (23) and zincophosphate microporous crystals (24) in reverse micelles has been studied. Pileni (23) demonstrated preparing nonspherical Cu particles by reducing the pure Cu salt of aerosol-OT (AOT) with hydrazine at ω O = 4 in the absence of aerosol-OT, where ω O is defined as the molar ratio of water to surfactant.…”

Synthesis of Silicalite-1 in Bicontinuous Microemulsion Containing AOT

“…They have used different quaternary amine surfactants in bulk aqueous medium. Dutta et al has reported the synthesis of microporous materials (zirconium phosphate) in reverse micelles at room temperature (8). Reports on the synthesis of zeolites in bicontinuous microemulsion are, however, very scarce (9a,b).…”

Controlled Growth of Gold Nanoparticles in Aerosol-OT/Sorbitan Monooleate/Isooctane Mixed Reverse Micelles

“…Pileni (23) demonstrated that nonspherical Cu particles can be prepared by reducing the pure Cu salt of Aerosol-OT with hydrazine at ω o = 4 in the absence of Aerosol-OT. Dutta et al (24) reported that the reverse micelles help nucleate the zincophosphate microporous crystals, and micellar interactions enable crystal growth by deposition along specific crystal faces.…”
