Titanium Nitride Nanocrystals on Nitrogen‐Doped Graphene as an Efficient Electrocatalyst for Oxygen Reduction Reaction

Through a facile synthetic process, a TiN/NG hybrid can be prepared as an efficient oxygen reduction reaction electrocatalyst in a four-electron pathway (see figure). It is low-cost and widely available and affords strong methanol tolerance and long-term durability. The synergistic chemical coupling effects between TiN and NG should be responsible for the excellent catalytic activity.
