具有多级异质结构的Bi2WO6/氧化物纤维布、方法及应用
摘要：
本发明是一种具有多级异质结构的Bi2WO6/氧化物纳米纤维布、制备方法及应用。本发明结合静电纺丝与醇热合成技术，制备了具有多级异质结构的Bi2WO6/TiO2或Bi2WO6/ZnO纤维布，其是由边长为50～200nm、厚度为10～40nm的Bi2WO6纳米片倾斜生长在直径为100～500nm并且相互有序交织的TiO2纤维或ZnO纤维上，其中Bi2WO6纳米片又是由尺寸为10～40nm的Bi2WO6纳米颗粒组成。本发明的具有多级异质结构的Bi2WO6/TiO2或ZnO纤维布具有较好的强度，较小的晶粒尺寸，较大的比表面积和多级的异质结构，在太阳能电池，光催化，自清洁等方面有重要的应用。
摘要（英）：

The invention relates to Bi2WO6/oxide nanofiber cloth with a multistage heterogeneous structure, a preparation method and application. The method combines the electrospinning and alcohol-thermal synthesis technology and prepares the Bi2WO6/TiO2 or Bi2WO6/ZnO fiber cloth with the multistage heterogeneous structure. The Bi2WO6 nanosheets with the side length of 50-200nm and the thickness of 10-40nm are grown on mutually orderly interwoven TiO2 fiber or ZnO fiber with the diameter of 100-500nm in an inclined manner, wherein, the Bi2WO6 nanosheets consist of Bi2WO6 nanoparticles with the dimension of 10-40nm. The Bi2WO6/TiO2 or ZnO fiber cloth with the multistage heterogeneous structure has the advantages of greater strength, smaller particle size, larger specific surface area and the multistage heterogeneous structure, thereby having important applications in solar cells, photocatalysis, self-cleaning and other aspects.
