Abstract Designing rational nanostructures of metal–organic frameworks based carbon materials to promote the bifunctional catalytic activity oxygen reduction reaction (ORR) and evolution (OER) is highly desired but still remains a great challenge. Herein, an in situ growth method achieve 1D structure‐controllable zeolitic imidazolate (ZIFs)/polyacrylonitrile (PAN) core/shell fiber (PAN@ZIFs) developed. Subsequent pyrolysis this precursor can obtain heteroatom‐doped nanofiber network as...
