Porous carbon nanofibers (PCNFs) are excellent one dimensional (1D) carbon materials that have fascinating applications in
the fields of gas separation, catalyst support, sensors, energy storage and conversion devices, due to their highly developed pore structure
and large surface area. Therefore, fabrication of PCNFs has attracted much attention, and many kinds of methods have been explored.
Recent developments in fabrication of PCNFs are summarized in the review. Their fundamental principles and process, applications, advantages
and disadvantages are discussed in detail.With careful preparation techniques, PCNFs with high specific surface area, hierarchical
and well-aligned pores can be obtained, and desired properties are also achieved. Finally, other issues regarding the technology
limitations of present methods for fabricating PCNFs, research challenges, and future trends are also discussed.
