Abstract Here first a 2D dual‐metal (Co/Zn) and leaf‐like zeolitic imidazolate framework (ZIF‐L)‐pyrolysis approach is reported for the low‐cost facile preparation of Co nanoparticles encapsulated into nitrogen‐doped carbon nanotubes (Co‐N‐CNTs). Importantly, reasonable Co/Zn molar ratio in ZIF‐L key to emergence microstructure. Specifically, high‐dispersed cobalt are fully tips N‐CNTs, leading full formation highly active Co–N–C moieties oxygen reduction evolution reactions (ORR OER). As...
