Abstract

Formation of Fe clusters in inverse micelles was studied. Iron salts are solubilized within the polar interior of inverse micelles, and addition of LiBH{sub 4} initiates reduction to produce monodisperse, nanometer-sized Fe based particles. The reaction sequence is sustained by material exchange between inverse micelles. Surfactant interface provides a spatial constraint on reaction volume, and reactions carried out in these micro-heterogeneous solutions produce colloidal sized particles (10--100 {Angstrom}) stabilized in solution against flocculation by surfactant. In this paper, the clusters were characterized using TEM, Moessbauer spectroscopy, electron diffraction, and x-ray photoelectron spectroscopy.

Synthesis and characterization of Fe colloid catalysts in inverse micelle solutions

Conference Martino, A; Stoker, M; Hicks, M

Surfactant molecules, possessing a hydrophilic head group and a hydrophobic tail group, aggregate in various solvents to form structured solutions. In two component mixtures of surfactant and organic solvents (e.g., toluene and alkanes), surfactants aggregate to form inverse micelles. Here, the hydrophilic head groups shield themselves by forming a polar core, and the hydrophobic tails groups are free to move about in the surrounding oleic phase. The formation of Fe clusters in inverse miscelles was studied.Iron salts are solubilized within the polar interior of inverse micelles, and the addition of the reducing agent LiBH{sub 4} initiates a chemical reduction tomore »« less

Synthesis and characterization of Fe and FeS[sub 2] (pyrite) catalyst particles in inverse micelles

Conference Martino, A; Wilcoxon, J; Sylwester, A; ...

Stock solutions of 10 wt. % surfactant are prepared in various organic solvents to produce the inverse micelle solutions. The iron salts are added directly to prepare 0.001--0.01M solutions, and are mixed overnight on a stirring plate to assure complete solubilization. Concentrated aqueous cadmium chloride solutions are mixed with the stock inverse micelles solutions to prepare 0.0005--0.M cadmium chloride microemulsions. To reduce the iron salts, the concentrated LiBH[sub 4]/THF solution is injected into the inverse micelle solutions under rapid stirring. To sulfide the iron and cadmium salts, the Li[sub 2]S/H[sub 2]0 solution is injected into the inverse micelle or microemulsionmore »« less

Encapsulation of metal nanocluster catalysts in silica materials via an inverse micelle/sol-gel synthesis

Technical Report Martino, A; Kawola, J; Yamanaka, S; ...

Nanometer sized metal particles were encapsulated in the micropores of xerogels and aerogels. The synthesis involves the sequential reduction of a metal salt followed by sol-gel processing in an inverse micelle solution. The inverse micelle solution solubilizes the metal salt and provides a micro-reactor for the nucleation, growth, and stabilization of the nanometer sized clusters. Hydrolysis and condensation of an added siloxane precursor produces a wet gel embedding the particles. Characterization of the particle size and composition and the particle growth process was completed with transmission electron microscopy (TEM), electron diffraction, and UV-visible absorption spectrometry. Characterization of the gel surfacemore »« less
