Electrospinning is a novel and efficient method by which fibers with nanoscale diameters are produced in a simple and sophisticated manner. In fact, this technique is the most popular route for producing nanofibers in variety of profiles including core/shell, porous and hollow nanofibers. Amongst numerous profiles, the hollow nanofibers due to higher specific area compared to normal nanofiber have found extensive applications in different areas such as sensors, solar cells, fuel cells, catalysts and also drug delivery. The current paper attempts to present a comprehensive review on different approaches for producing hollow nanofibers based on electrospinning with no nozzle and equipped with one needle and coaxial needle. In the final part, a specific attention has been paid on conductive hollow nanofibers. Furthermore, the classified information regarding various characterization techniques including microscopy and spectroscopy is reported for detail investigation on hollow nanofiber. Diverse applications of hollow nanofiber based on appropriate studies are also presented.
