Copper Metallic Particles Synthesized "in Situ" in Reverse Micelles: Influence of Various Parameters on the Size of the Particles
Control of the size of metallic Cu particles formed in reverse micelles of AOT (sodium bis(2-ethylhexyl)-sulfosuccinate) was achieved by varying water content, reagent concentration, and intermicellar interactions. In the 1-12 nm range, the size of metallic Cu particles can be deduced from the measu...

| Summary: | Control of the size of metallic Cu particles formed in reverse micelles of AOT (sodium bis(2-ethylhexyl)-sulfosuccinate) was achieved by varying water content, reagent concentration, and intermicellar interactions. In the 1-12 nm range, the size of metallic Cu particles can be deduced from the measure of the optical densities at two wavelengths. It was demonstrated that the size of the metallic copper particle depends upon the number of Cu ions and reducing agents per micelle. In particular, it was observed that decreasing intermicellar attractions decrease the crystallite size. |
