Abstract
Cobalt porphyrins in which Ru(NH_3)_5^(2+) groups are coordinated to four cyanophenyl ligands pendant to the porphyrin ring act as catalysts for the electroreduction of O_2 when adsorbed on the surface of graphite electrodes. The parent 4-cyanophenyl derivative catalyzes the four-electron reduction of O_2 to H_2O, but the 4-cyano-2,6-dimethylphenyl derivative catalyzes only the two-electron reduction of O_2 to H_2O_2.
