通过控制预合成的Au纳米晶在ZnO结构表面的沉积，得到了独特的藕状Au-ZnO杂化结构。首次采用水热法制备了具有莲藕状结构的氧化锌。我们还详细研究了不同Au含量对光催化活性的影响。值得注意的是，与纯ZnO组分相比，这些具有适量Au含量的所得莲藕状Au-ZnO纳米结构表现出更好的光催化效率。
Unique lotus-rootlike Au-ZnO hybrid structures were obtained by controlling the deposition of pre-synthesized Au nanocrystals onto the surfaces of as-obtained ZnO structures. ZnO with lotus-rootlike structures was first prepared through a hydrothermal process. We also investigated the effects of various Au contents on the photocatalytic activities in detail. Notably, compared to the pure ZnO component, these resulting lotus-root-like Au-ZnO nanostructures with the appropriate amounts of Au content exhibited better photocatalytic efficiency.
