Abstract
Transition metal–nitrogen–carbon materials are used as catalysts for the oxygen reduction reaction (ORR) because of their low cost, high activity, and stability in the alkaline medium. Herein, CoZn/nitrogen–carbon (NC)–Ti3C2 as an ORR electrocatalyst is prepared by one‐step pyrolysis of zeolitic imidazolate framework (ZIF)‐67/ZIF‐8 on the Ti3C2 surface. The CoZn/NC–Ti3C2 catalyst presents considerable kinetics with a half‐wave potential (E1/2) of 0.847 V, and the fuel cell peak power density reaches 245 mW cm−2. Furthermore, this catalyst exhibits an excellent stability with only 4.83% drop of relative current after 30000 s of testing. Herein, a new strategy for high‐effective and high‐stability non‐precious metal catalysts for anion exchange membrane fuel cells is provided.
