One　of　the　urgent　problems　in　the　commercialization　of　fuel　cells　is　the　high　cost　of　electrode　materials　due　to　the　use　of　Pt/C　as　the　catalyst　for　oxygen　reduction　reaction　(ORR).　Herein,　by　taking　advantages　of　the　metal-organic　frameworks,　a　novel　ORR　catalyst　of　Co@Co9S8-N/C　with　composite　porous　structure　is　synthesized　with　a　facile　coprecipitation-pyrolysis　method.　Co@Co9S8-N/C　is　composed　of　graphitic　carbon　skeleton　with　Co9S8　covered　Co　nanoparticles　(Co@Co9S8)　and　nitrogen　atoms　doping　on,　on　which　Co@Co9S8　and　pyridinic　N　provide　catalytic　sites　for　ORR.　The　N,　S　doped　surrounding　graphitic　carbon　skeleton　after　pyrolysis　and　vulcanization　processes　can　protect　the　electrochemical　active　sites　from　deactivation.　The　fabricated　Co@Co9S8-N/C　with　abundant　catalytic　active　sites　performs　excellent　ORR　activity　and　stability.　Thereafter,　the　structure　of　the　Co@Co9S8-N/C　is　optimized　by　changing　the　Zn/Co　ratio　in　the　precursor　to　improve　its　ORR　performance.　The　results　show　that　with　the　Zn/Co　ratio　of　3:2,　Co@Co9S8-N/C　gives　the　best　ORR　activity　relying　on　its　well　specific　surface　area,　sufficient　and　uniform-dispersed　catalytic　sites.　Based　on　this,　the　Co@Co9S8-N/C　catalytic　alkaline　direct　glucose　fuel　cells　perform　better　than　the　Pt/C　catalytic　one.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
