摘要：

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).
