Zeolitic imidazolate frameworks (ZIFs) are attracting considerable attention in CO2 capture, gas storage/separation as well as size selective catalysis.However, the research concerning their potential applications for oxygen electrochemical reduction (ORR) of Pt-ffee electrocatalysts has not been reported so far, which might be due to a great challenge in electronic conductivity and well-designed catalysis structures.It is the first time that we developed a new Pt-free electrocatalysts composed of cobalt nanoparticles and dodecahedron carbon matrix which were obtained by heat treatment of ZIF-67.
