Tóm tắt

The construction of freestanding carbon nanofiber membrane with single-atomic metal active sites and interconnected microchannels as air electrodes is vital for boosting the performance of zinc-air batteries (ZABs). Herein, single-atomic Fe sites is prepared on freestanding hierarchical nitrogen/phosphorus co-doped carbon nanofibers (Fe SACs@PNCNFs) by loading Fe-doped zeolitic imidazolate framework-8 with leaf-like structures on electrospun polyacrylonitrile (PAN) nanofibers with subsequent multi-step pyrolysis in the presence of sodium monophosphate, which are confirmed to be in the form of Fe-N
