Abstract: Compositional and structural engineering of metal-metalloid materials can boost their electrocatalytic performance. Herein, a highly efficient and stable electrocatalytic system for the oxygen reduction reaction is obtained by creating heterointerfaces between N-doped carbon and cobalt boride nanosheets. Furthermore, a detailed investigation on the effect of annealing temperature as well as the amount of carbon and nitrogen sources is conducted to tune their performance. The best electrocatalyst among the prepared materials is found to have an onset potential of 1.05 V and half-wave potential of 0.94 V, which are 40 and 72 mV positive in comparison to commercial Pt/C, respectively. Finally, a zinc–air battery is also assembled using the catalyst.
