BiOI纳米片/TiO2纳米纤维复合结构的构筑及其可见光催化性能研究
|
Abstract:
通过电纺技术与溶剂热方法的相结合，制备了BiOI纳米片/TiO2纳米纤维复合异质结构(BiOI/TiO2)。BiOI纳米薄片在电纺TiO2纳米纤维表面密集均匀地复合，所得复合结构具有较高的活性面积和分立结构，表现出较强的可见光催化活性。实验证明，BiOI/TiO2复合结构的可见光催化活性明显优于纯的TiO2纳米纤维和BiOI纳米薄片。此外，由于BiOI/TiO2复合结构所具有纳米纤维网毡结构，使其在污水处理领域展现了潜在的应用价值。
BiOI nanosheet/TiO2 nanofiber composite structure (BiOI/TiO2) was prepared by combining electrospinning technology with solvothermal method. BiOI nanosheets were densely and uniformly composite on the surface of electrospun TiO2 nanofibers, and the resulting composite structures had higher active area and discrete structure, showing a strong visible light catalytic activity. Experimental results showed that the visible light catalytic activity of BiOI/TiO2 composite structure was significantly better than that of pure TiO2 nanofibers and BiOI nanosheets. In addition, BiOI/TiO2 composite structure has potential application value in the field of wastewater treatment due to its nanofiber mesh structure.
