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.
