Fe, N, S-doped porous carbon as oxygen reduction reaction catalyst in acidic medium with high activity and durability synthesized using CaCl2 as template

Fe, N, S-doped porous carbon was synthesized by direct carbonization of a mixture of melamine formaldehyde resin and Fe(SCN)3 using CaCl2 as a template. The porous carbon showed high activity and durability in the oxygen reduction reaction.
