Abstract:

Larger specific surface area, richer interfacial composition, and more efficient mass transfer paths are the keys to constructe multi-component catalytic systems and improve catalyst efficiency. Hollow nanofibers with multiple cavity structures show great capability to adjust their specific surface area and interface composition, and become an ideal platform for preparing highly efficient heterogeneous catalysts. The development of electrospinning technology provides a simple and efficient method for the controllable preparation of hollow nanofibers, and effectively promotes the structural innovation and application expansion of hollow nanofibers. In this review, the unique advantages of hollow nanofiber materials with different composition and morphology prepared by electrospinning in the application of catalysis(including photocatalysis, electrocatalysis and thermocatalysis) are summarized from three aspects: construction strategies, structural characteristics and the corresponding relationship between structure and performance. Firstly, the different structural forms of hollow nanofibers prepared by innovative electrospinning methods combined with subsequent processes are demonstrated, and then the research progress of constructing high-efficiency catalysts based on hollow nanofibers are reviewed. Finally, the future development trends of the applications of hollow nanofibers in the field of catalysis are summarized and prospected to provide a useful reference for the design of high-efficient heterogeneous catalysts.
