The solid, hollow, and tube‐in‐tube porous nanofiber structures of TiO 2 are synthesized successfully by a simple non‐coaxial electrospinning method without using a complicated coaxial jet head, combined with adjusting the concentration of the TiO 2 precursor and the pinhole diameter of the jet head and by final calcination. The formation mechanisms of different structured TiO 2 fibers are discussed in detail. This method is facile and effective, and easy to scale up. Furthermore, it is a versatile method for constructing tube‐in‐tube fibers of other metal oxides such as ZrO 2 , SiO 2 , SnO 2 , and In 2 O 3 . The photocatalytic activity of tubular TiO 2 nanofibers for the degradation of 2‐chlorophenol and 2,4‐dichlorophenol under UV or visible‐light irradiation is better than the one of commercial available TiO 2 powder, rutile, and anatase TiO 2 fibers.
