dc.description.abstract | We report new structural designs to dramatically increase the surface area of the ZnO nanostructure without compromising the small volume much. Space-efficient and facet-specific ZnO 3-D nanostructures, namely {10 (1) over bar1}-stacked nanocones and {10 (1) over bar0}-nanoforest, have been prepared by facet-selective etching and oriented nanocrystal growth, respectively. Grain boundary etching of multiwalled ZnO hexagonal nanocones leads to polar {10 (1) over bar1} facet-maximized ZnO stacked nanocones and oriented nanocolumn growth on ZnO hexagonal nanocones generates {10 (1) over bar0} facet maximized ZnO nanoforests. These facet-specific ZnO nanostructures offer opportunities for examination of their facet-dependent photocatalytic properties. Compared to the original ZnO hexagonal nanocone structures, these new ZnO 3-D structures exhibit a much higher photocatalytic property for photodegradation of organic dye, rhodamine B. Specifically, {10 (1) over bar1} stacked nanocones with a polar {10 (1) over bar1} plane maximized structure and high density of oxygen vacancies have shown the best performance among structures examined. We also demonstrate a great photocatalytic performance of the Au supported 3-D ZnO nanostructures with well-defined facets and high surface area. | - |
