摘要：With fuel cells gaining recognition as promising devices for directly converting the chemical energy to electricity, to develop low-cost catalysts for electrocatalysis of oxygen reduction reaction (ORR) has become an active topic in this field. Hierarchical porous carbon materials (HPC) doped with heteroatoms, for instance N, S and Fe, are promising materials for using as catalysts for the ORR due to their low cost, high stability and high efficiency. In this work, we report a low-cost, facile and scalable method to produce nitrogen-doped hierarchical porous carbon material (N-HPC) by pyrolysis of corncobs. The activated N-HPC catalysts exhibit high activity for ORR compared to that of the state-of-the-art commercial Pt/C catalysts.
