Abstract
In this work we present a simple procedure for the production of gold atomic clusters by means of a modification of the Brust’s two-phase method, using tetrahexylammonium bromide as capping agent. The gold atomic clusters obtained have the following formula: Aun, with \(3 \leq \textit{n} \leq 13\), where n is the number of gold atoms per cluster. We report the formation of different species at different stages of the reduction reaction. Au clusters were characterized by TEM, MALDI-TOF mass spectrometry and UV-vis spectroscopy. Gold clusters are stable in solution after several years of preparation.
