✦ Synopsis

Composite

Au/TiO 2 nanoparticles were synthesized using TiO 2 nanoparticles as nuclei. The particles were characterized by UV-vis spectroscopy, ζ 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 ζ potential is +31.3 mV. Monolayers of composite Au/TiO 2 nanoparticles were obtained using the potentiostatic technique.
