Abstract :
In this paper, ZnO ultrafine particles (UFPs) were prepared by the thermal decomposition method of the precursor, zinc carbonate hydroxide. The structure and properties of the as-prepared ZnO UFPs were studied using TEM, XRD, BET, SPS, ESR, Raman, XPS and UV–Vis absorption spectroscopy. It was found that the prepared ZnO UFPs exhibited obvious quantum size effect and surface effect. In addition, there were many active species on the surface of ZnO UFPs such as oxygen deficiencies and hydroxyls, both of which can improve the photocatalytic activities of ZnO UFPs.
