摘要
A novel echinops-like Ni@NiNC composite has been successfully fabricated by direct pyrolysis of a folic acid-Ni complex. It was elucidated that the co-existence of Ni and Ni-N active sites could promote the catalytic activity of ORR and OER simultaneously. Essentially, the unique echinops-like structure with hierarchical porous morphology has indispensable contribution to charge transportation and exposure of active sites to O-2 adsorption when assembled into a rechargeable zinc-air battery.
