Efficient Oxygen Reduction Reaction Using Ruthenium Tetrakis(diaquaplatinum)Octacarboxyphthalocyanine Catalyst Supported on MWCNT Platform

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...

Description
Summary: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.
