Vulcan XC-72 treated by nitric acid is employed as an oxygen reduction reaction (ORR) catalyst. The carbon catalyst exhibits higher electrocatalytic activity and stability in 6[Formula: see text]mol[Formula: see text]L[Formula: see text] KOH electrolyte. The current density for oxygen reduction is 45[Formula: see text]mA[Formula: see text]cm[Formula: see text] at [Formula: see text][Formula: see text]V (vs. HgO/Hg). A zinc–air battery using XC-72 carbon electrode was assembled, the discharge voltage could reach up to 0.6[Formula: see text]V under a high current density of 80[Formula: see text]mA[Formula: see text]cm[Formula: see text].
