Non-precious　metal　nitrogen-carbon　composites　(M-N-C)　derived　from　ZIFs　are　an　excellent　non-precious　metal　catalyst　for　use　in　energy　conversion　and　storage　devices　such　as　fuel　cells　and　metal-air　batteries.　Herein　ZIF-67　precursor　with　good　dispersion,　perfect　crystal　structure　and　size　of　below　270　nm　was　synthesized　by　consuming　low　amount　of　2-methylimidazole　ligand　using　a　mixture　of　ethanol　(EA)　and　methanol　(MT)　as　the　reaction　medium.　Compared　with　the　traditional　method　of　reducing　the　size　of　ZIF　-67　by　increasing　the　amount　of　ligands　in　methanol,　this　method　avoids　the　waste　of　raw　materials　and　saves　the　cost.　The　Co-N-C-MT/EA　catalysts　derived　from　ZIF-67　exhibits　good　ORR　activity　in　alkaline　media　(0.1　M　KOH)　with　a　half-wave　potential　of　0.81　V　vs　RHE.　After　5000　cycles,　the　initial　potential　and　half-wave　potential　basically　remain　no　change,　showing　excellent　long-term　stability.　And　remarkable　me-thanol　resistance　is　also　displayed　comparing　with　commercial　Pt/C.　The　present　experimental　result　shows　that　the　improved　synthesis　method　of　ZIF-67　precursors　has　far-reaching　implications　for　the　field　of　catalyst　research.(c)　2022　Elsevier　B.V.　All　rights　reserved.
