Iron (II) tetrakis(diaquaplatinum) octacarboxyphthalocyanine supported on multi-walled carbon nanotubes as effective electrocatalyst for oxygen reduction reaction in alkaline medium

Oxygen reduction reaction (ORR) in alkaline medium at iron (II) tetrakis (diaquaplatinum) octacarboxyphthalocyanine (PtFeOCPc) catalyst supported on multi-walled carbon nanotubes (MWCNTs) has been described. The ORR followed the direct 4-electron transfer process, with a very low onset potential (ap...

Description
Summary:Oxygen reduction reaction (ORR) in alkaline medium at iron (II) tetrakis (diaquaplatinum) octacarboxyphthalocyanine (PtFeOCPc) catalyst supported on multi-walled carbon nanotubes (MWCNTs) has been described. The ORR followed the direct 4-electron transfer process, with a very low onset potential (approximately zero volts vs. Ag|AgCl, saturated KCl) and at a kinetic rate constant, 2.78 × 10 − 2 cm s − 1 . The results clearly showed that the ORR activity at the MWCNT-PtFeOCPc platform is comparable or even better than recent reports with other electrocatalysts, thus a promising catalytic platform for cathodic process in fuel cell device.
