a, Schematic for fabrication of the zinc–air battery. The electrolyte used was 6 M KOH with 0.2 M zinc acetate and a polished Zn foil was used as the anode. The air-cathodes for Zn-air battery were prepared by coating the catalysts on a hydrophobic carbon paper. b, Photograph of the zinc-air battery.
