Abstract:

To provide experimental data and theoretical basis for the preparation of subsequent porous carbon nanofibers, the latest research progress on the feasibility of industrialization by electrospinning preparatio methods, pore struture tpes and application of electrospun porous carbon nanofibers at home and abroad were reviewed. Two kinds of preparation methods and their principles of electrospun porous carbon nanofibers including blending of polymer and polymer and blending of polymer and inorganic particles are expounded, and the structural characteristics of the porous carbon nanofibers prepared by these methods were also described. Then, according to the shape of the hole structure, the structure types of porous carbon nanofibers were divided into hollow, mesoporous, hierarchical pore and carbon shell-honeycomb core, etc. Finally, the application prospects in the fields of electrochemistry, hydrogen storage, catalysis and adsorption, and the future perspectives for porous carbon nanofibers were concluded as well.

Key words: porous nanofiber, carbon nanofiber, electrospinning, preparation method, pore structure
