采用简单的浸渍-煅烧法制备了具有蝴蝶翅膀分级结构的仿生Bi 2 WO 6（morph-Bi 2 WO 6）。结果表明，仿生方法可以有效地控制Bi 2 WO 6晶体的组成和结构，并保持了纯斜方晶系Bi 2 WO 6晶体的纳米级结构。反射光谱表明，与相同条件下合成的Bi 2 WO 6粉末相比，由于其具有分级结构，morph-Bi 2 WO 6在可见光下的吸收性能得到了改善。该策略有望扩展到其他三元化合物材料，在水分解和光催化剂方面具有潜在的应用。
Biomimetic Bi2WO6with hierarchical structures inherited from butterfly wings (morph-Bi2WO6) were fabricated by a simple soaking and calcinating method. The hierarchical structures down to nanometer level were retained in the resultant morph-Bi2WO6with pure orthorhombic phase, indicating that our biomimetic approach is effective in controlling the composition and structure of Bi2WO6. The reflectance spectra showed an improved absorption property of morph-Bi2WO6under visible light over the Bi2WO6powder synthesized under the same condition without butterfly wings, owing to the hierarchical structures. The strategy is expected to extend to other ternary compound materials for potential applications in water splitting and photocatalyst.
