Peroxide production: Electrocatalysts of CoCl 2 (ligand)/XC‐72 heat‐treated in He at 973 K are examined. N ‐bidentate ligands of 1,10‐phenanthroline and 2,2′‐bipyridine are efficient for the formation of neutral H 2 O 2 at 278 K. It is proposed that Co on a bidentate N ‐coordination site at the carbon surface (CoN 2 C x ) is the active site for O 2 reduction and H 2 O 2 formation.
