By pyrolyzing cattle bones, hierarchical porous carbon (HPC) networks with a high surface area (2520 m 2 g −1 ) and connected pores were prepared at a low cost and large scale. Subsequent co‐pyrolysis of HPC with vitamin B12 resulted in the formation of three‐dimensional (3D) hierarchically structured porous cobalt–nitrogen–carbon (Co‐ N ‐HPC) electrocatalysts with a surface area as high as 859 m 2 g −1 as well as a higher oxygen reduction reaction (ORR) electrocatalytic activity, better operation stability, and higher tolerance to methanol than the commercial Pt/C catalyst in alkaline electrolyte.
