Abstract
A heteroatoms-doped hollow biocarbon spheres with high surface area and hierarchical porous structure were successfully prepared by hydrothermal treating and followed pyrolyzing the mixture of brewer's yeast powder, ferric chloride and ammonium hydroxide. The catalyst displays excellent ORR catalytic activity in alkaline medium, with a 28Â mV positive shift (0.861 vs. 0.833Â V) in half-wave potential compared to that of commercial 20Â wt.% Pt/C (JM)297.
