We demonstrate a new approach for synthesizing Ag-ZnO heterogeneous nanostructures in which single-crystalline ZnO nanorods were selectively grown on {111} rather than {100} facets of single-crystalline Ag truncated nanocubes. We have identified the fine structure of the Ag-ZnO heterostructures and proposed a mechanism indicating that structure match plays a critically important role in this type of facet-selective growth. These heterogeneous nanostructures are of special interest and have potential applications in electrical contacts, functional devices, biological sensors, and catalysis.
我们展示了一种合成Ag-ZnO异质纳米结构的新方法,其中单晶ZnO纳米棒选择性地生长在单晶Ag截顶纳米立方体的{111}面而非{100}面上。我们已经确定了Ag-ZnO异质结构的精细结构,并提出了一种机制,表明结构匹配在这种面选择性生长中起着至关重要的作用。这些异质纳米结构具有特殊的意义,在电接触、功能器件、生物传感器和催化领域具有潜在应用。
