Bi(4)Ti(3)O(12) nanofibers with diameters of 50-100 nm have been fabricated for the first time through a simple and economical technique of electrospinning combined with subsequent calcination. The as-formed Bi(4)Ti(3)O(12) nanofibers are porous and composed of inter-linked nanoparticles of 30-50 nm in size. They exhibit both enhanced visible-light-driven photocatalytic decomposition of rhodamine B (RhB) and favorable recycling capability. It is attributed to not only the macrostructure, such as the morphology, surface texture, and grain shape, but also the intrinsic structures of oxygen vacancies and surface adsorbed oxygen.
首次通过简单且经济的静电纺丝技术结合后续煅烧法制备出了直径为 50-100nm 的 Bi(4)Ti(3)O(12)纳米纤维。所形成的 Bi(4)Ti(3)O(12)纳米纤维具有多孔性,由 30-50nm 大小的相互连接的纳米颗粒组成。它们不仅表现出增强的可见光驱动罗丹明 B(RhB)的光催化分解性能,而且还具有良好的可回收能力。这归因于不仅是宏观结构,例如形态、表面纹理和晶粒形状,还有氧空位和表面吸附氧的本征结构。
