Effect of Solvent and Reagent Ratio on the Size of Gold Nanoparticles in Nanocomposites Formed in the Redox Reaction of H[AuCl.sub.4] with Two-Dimensional MoS.sub.2

It was shown that the redox reaction of tetrachloroauric acid with exfoliated molybdenum disulfide leads to the formation of Au@MoS.sub.2nanocomposites containing nanoparticles of metallic gold. The reduction rate of the gold(III) is higher in dimethylformamide than in N-methylpyrrolidone. It was sh...

Description
Summary:It was shown that the redox reaction of tetrachloroauric acid with exfoliated molybdenum disulfide leads to the formation of Au@MoS.sub.2nanocomposites containing nanoparticles of metallic gold. The reduction rate of the gold(III) is higher in dimethylformamide than in N-methylpyrrolidone. It was shown that the size of the nanoparticles can be controlled by varying the concentration ratio of the reagents from 2 : 1 to 5 : 1, and under the investigated conditions it increases stepwise from 6.5 to 13 nm.
