The formulation of optoelectronic components into 1D nanostructures allows the promotion of new materials with multifunctionalities. In this work, it is demonstrated that new synthesis of photocatalytic carbon nanofiber decorated with semi‐embedded titanium oxide (TiO₂), namely, TiO₂@carbon fiber, is conveniently accessed through the electrospinning of polyacrylonitrile polymer and TiO₂ particle comixture, and then followed by photon‐activated self‐erosion to expose the embedded TiO₂ and carbonization. The hybrid nanofibers are characterized by field emission scanning electron microscopy, transmission electron microscopy, and X‐ray diffraction analysis. Furthermore, the photocatalytic activities of the resultant fibers are tested with photodegradation of Rhodamine B in aqueous solution, which reveals that the carbon nanofiber with semi‐embedded TiO₂ drastically improved catalytic efficiency and recyclability, comparing to those fibers without or with embedded TiO₂.

通过电纺丝具有半嵌入式氧化钛颗粒的功能碳纳米纤维

将光电组件制成一维纳米结构，可以推广具有多功能性的新材料。在这项工作中，证明了通过聚丙烯腈聚合物和TiO ₂颗粒混合物的电纺丝可以方便地获得用半嵌入式二氧化钛（TiO ₂）装饰的光催化碳纳米纤维的新合成方法，即TiO ₂ @碳纤维。然后进行光子活化自腐蚀以暴露出嵌入的TiO ₂和碳化。杂化纳米纤维的特征在于场发射扫描电子显微镜，透射电子显微镜和X射线衍射分析。此外，通过罗丹明B在水溶液中的光降解测试了所得纤维的光催化活性，这表明与未嵌入TiO ₂或嵌入TiO _2的那些纤维相比，具有半嵌入TiO ₂的碳纳米纤维可以显着提高催化效率和可回收性。
