dc.description.abstractCu nanoparticles were formed on surface of nano-ZnO by UV light induced photoreduction of CuCl2 in
methanol solution suspended with ZnO nanoparticles. By controlling the reaction conditions, the average
size of the produced copper nanocrystal can be fine-tuned in the range of 10–200 nm. At constant UV
irradiation, the Cu nanocrystals gradually grew up as the initial concentration of copper cation was
increased, showing that the in situ formed Cu nanoparticles act as a bridge to facilitate the transferring of
photoexcited electrons from ZnO surface to Cu2+ in solution. A Redox property was also proved for the
Cu nanoparticles.
