摘      要：Three-dimensional （3D） center-hollow star-like ZnO architectures have been successfully fabricated on a large scale using Zn（acac）2 （acac= acetylacetone） and ethylenediamine as starting reactants via a surfactant-assisted hydrothermal technique. Field emission scanning electron microscopy （FESEM） images show that the 3D star-like ZnO architectures are center-hollow, which are composed of hexagonal conic nanotubes. The contrastive experiments results indicate that the introduction of surfactant （PVP or PEG） was indispensable in controlling the growth of star-like ZnO with hollow structure. A possible formation mechanism was proposed. Fig.2. FESEM images of the as-prepared ZnO products: （a,b） using PVP as surfactant and （c,d） Using PEG10000 as surfactant
