Abstract: | The formation of gold nanoparticles and clusters in solutions of reverse micelles formed by Tritons X-45, X-114, and X-100
(polyoxyethylene isooctylphenyl ethers with degrees of polymerization n = 5, 7–8 and 9–10, respectively) in the presence of sodium sulfite is studied. The stability of these particles is shown
to depend on the length of ethylene oxide chains in surfactant molecules, water content in micelles, and the presence of special
additives. It is found that, on one hand, L-ascorbic acid favors a reduction of HAuCl4 and, on the other hand, affects the stability of resultant particles. |
