| Outline of Annual Research Achievements |
In this project, we have devoted to fabricating high-performance carbon-based electrode materials for electrochemical capacitance, electrochemical catalysis, and rechargeable batteries. We rationally designed MOF-derived carbon-based materials with controlled 2D/3D morphologies, doped heteroatoms, and encapsulated functional nanosheets, which were quite important and of great interest from the viewpoint of synthetic chemistry and practical electrochemical applications. ZIF-incorporated hybrid polymeric fibres were fabricated by using a dual‐phase electrospinning method. These were then transformed into Co3O4‐nanoparticle‐decorated porous N‐doped carbon fibres (ZIF‐Co3O4/NCF) through multi‐step annealing treatment. The resultant ZIF‐Co3O4/NCF was interweaved into a self‐supported film and could be used as a bi‐functional catalyst for catalysing oxygen reduction in both aqueous and non‐aqueous electrolytes. Electrochemical tests demonstrate that ZIF‐Co3O4/NCF displayed a high catalytic activity for oxygen reduction with a half‐wave potential (E1/2) of 0.813 V (vs. RHE) and an almost favourable four‐electron reduction pathway in alkaline medium.
