Popis:	Electrocatalytic reduction of molecular oxygen in alkaline solution using a novel ruthenium tetrakis(diaquaplatinum)octacarboxyphthalocyanine (RuOCPcPt) electrocatalyst supported on multi-walled carbon nanotube electrode has been described. We show that the oxygen reduction activity follows a direct 4-electron transfer process at high kinetic rate constant, 3.57×10−2 cm s−1.
