Herein, we report a new electrocatalyst for the oxygen reduction reaction derived from a bimetallic metal–organic framework and single‐walled carbon nanohorns. Owing to the 3D conductive network offered by the nanohorns, this type of catalyst exhibits comparable performance with the commercial 20 % Pt/C catalyst as well as excellent durability and methanol tolerance at the half‐cell test in an alkaline medium. Moreover, the new electrocatalyst shows higher peak power density (185 mW cm−2) than that of Pt/C (160 mW cm−2) in addition to a comparable stability in a real Zn–air battery test. A correlation between the value of the peak power densities and pore structures of some parallel samples is studied in detail.
