- 中文摘要: Alkanethiols were introduced to study their influence on the oxidized Cu colloids. The XPS measurements have been performed to characterize Cu identities in various stages, i.e. freshly prepared Cu, aged Cu, and aged Cu mixing with alkanethiols. The aged colloidal solutions resulted in CuO growth. The adsorption of alkanethiols on the oxidized copper reduced Cu2+ to Cu1+ with the formation of surface thiolates. Based on the TEM images, addition of alkanethiols yielded a distinct change in the colloidal appearance from aggregation to dispersion.
