摘要：

Composite Au/TiO2 nanoparticles were synthesized using TiO2 nanoparticles as nuclei. The particles were characterized by UV-vis spectroscopy, zeta potential, EDS, and TEM. The mean diameter of the particles is about 23.6 nm, and the position of the surface plasma absorption band peak is at 533 nm, with a red shift of 15 nm compared with that of Au sol, The zeta potential is +31.3 mV, Monolayers of composite Au/TiO2 nanoparticles were obtained using the potentiostatic technique.
