Efficient MnO and Co nanoparticles coated with N-doped carbon as a bifunctional electrocatalyst for rechargeable Zn-air batteries

Compositional engineering of perovskite oxide BaCo0.5Fe0.5O3−δ as an efficient bifunctional electrocatalyst for rechargeable zinc–air batteries

“…Therefore, it is highly urgent to develop a novel bifunctional electrocatalyst to simultaneously accelerate the ORR/ORE bifunctional kinetics and promote the practical application of ZABs. [27][28][29][30][31][32] Researchers have explored a series of bifunctional oxygen electrocatalysts, such as heteroatom doped carbon, 33,34 defect-induced carbon, 35,36 single-atom catalysts, 37,38 and transition metal oxide/hydroxide/nitride/sulfide catalysts. 39,40 Perovskite oxides (ABO 3 ) have become a promising class of bifunctional oxygen electrocatalysts due to their unique electronic structure, low price, diverse variety, high catalytic activity and flexible composition.…”
