Paper Title:
Oxygen Reduction Electrocatalysts Based on Two-Dimensional Iron Polyphthalocyanine
  Abstract

Two-dimensional iron polyphthalocyanine(PPcFe) was synthesized by heating iron (II) phthalocyanine tetracarboxylic acids at 400°C in argon atmosphere. The polymer was characterized and analyzed by UV-Vis, FT-IR, XRD and TG. UV-Vis absorption spectra of iron phthalocyanine showed that absorption bands appeared at higher wavelengths than monomer phthalocyanine. The result of IR indicated that the absorption peaks corresponding to the carboxylic acid groups decreased and the characteristic phthalocyanine ring absorption bands were observed. The DTA data for PPcFe showed exceptional thermal stability. PPcFe, monomer phthalocyanine(PcFe) and dinuclear iron phthalocyanine(DPcFe) were adsorbed on the Vulcan XC-72 carbon and then heat-treated at 400°C in argon atmosphere to prepare catalyst. The electrocatalytic activity was investigated using linear scan voltammetry(LSV) in 0.5M H2SO4. The polarisation curve of oxygen reduction on the FePPc/C catalyst in O2-saturated H2SO4 was compared to that obtained on PcFe, DPcFe and platinum catalysts. Results showed that it possessed higher catalytic activity than PcFe and DPcFe catalysts. LSV at different electrode rotation rates led to determine the Koutecky-Levich plots from which it was shown that the kinetic parameters for the ORR at FePPc/C electrodes are similar to those obtained at 30wt% Pt/C.
