Fiber Materials for Electrocatalysis Applications

Fiber materials are promising for electrocatalysis applications due to their structural features including high surface area, controllable chemical compositions, and abundant composite forms. In the past decade, considerable research efforts have been devoted to construct advanced fiber materials possessing conductive network (to facilitate efficient electron transport) and large specific surface area (to support massive catalytically active sites) to boost electrocatalysis performance. Herein, we focused on recent advances in fiber-based electrocatalyst with enhanced electrocatalytic activity. Moreover, the synthesis, structure, and properties of fiber materials and their applications in hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, carbon dioxide reduction reaction, and nitrogen reduction reaction are discussed. Finally, the research challenges and future prospects of fiber materials in electrocatalysis applications are proposed. Graphical abstract: [Figure not available: see fulltext.]
