Graphitic carbon is the key: A Pt catalyst that is supported on carbon nanocages with a graphitic structure is found to exhibit not only a high catalytic activity, but also a superior thermal stability and electrochemical durability in harsh operating conditions when compared with a counterpart that is supported on conventional carbon black (see graphic).
