Current events: A phosphorus‐doped, graphite layer catalyst without any metal residue has been developed that shows high electrocatalytic activity, long‐term stability, and excellent tolerance to cross‐over effects of methanol in the oxygen reduction reaction. The oxygen reduction current densities of the glassy carbon (GC) electrode modified by the P‐doped graphite (see red line in the picture) are much larger than those of the unmodified (blue line) and the GC electrode modified by a platinum–carbon catalyst (data not shown).
