Carbon Monolith

A series of three-dimensional N-doped hierarchical macro- and meso-porous carbon monoliths (NCMs), which were prepared successfully using a facile nanocasting strategy in combination with pyrolysis in NH3, showed comparable catalytic activity but superior durability and methanol tolerance to Pt/C for the oxygen reduction reaction.
