Preparation of 2-Quinolinethiol Capped Gold Nanoparticles and Its Electrochemical Properties

Abstract

Abstract: 2-Quinolinethiol was employed as one stabilizer to produce 8—10 nm gold nanoparticles. UV-Vis spectrum confirmed the surface plasmon absorbance and in comparison with alkanethiolate-gold nanoparticles with the same size, the blue shift in absorbance peak was interpreted as the free electron transferred from N to gold core. Cyclic voltammograms proved that the reduction potential of 2-quinolinethiol was not altered as it assembled onto gold nanoparticles, however there appeared an obvious hysteresis in oxidation current, which was attributed to the oxidation ability of quinoline reduction product.

Key words: Quinoline, Gold nanoparticles, Electrochemistry
