Oxidation of CO on a Pt-Fe alloy electrode studied by surface enhanced infrared reflection-absorption spectroscopy

Article Abstract:

Research is presented demonstrating the use of the attenuated total reflection technique of surface-enhanced infrared reflection-absorption spectroscopy, together with cyclic voltammogram measurement, to observe the oxidation of adsorbed CO on a Pt-Fe alloy.

In-situ ATR-FTIR spectroscopic study of electro-oxidation of methanol and adsorbed CO at Pt-Ru alloy

Article Abstract:

The attenuated total reflection technique (ATR) FTIR spectroscopy identifies adsorbed species such as CO(sub L), CO(sub B), COO(super -), and particularly absorbed water during themethanol oxidation reaction (MOR) at the sputtered Pt-Ru film electrode. The results are believed to accelerate the development of new DMFC anode catalysts.

Temperature dependence of oxygen reduction activity at Pt-Fe, Pt-Co, and Pt-Ni alloy electrodes

Article Abstract:

Oxygen reduction reaction activity and H(sub 2)O(sub 2) formation at Pt(sub 54)Fe(sub 46), Pt(sub 68)Co(sub 32), and Pt(sub 63)Ni(sub 37) electrodes in 0.1 M HClO(sub 4) solution at 20 to 90 degree Celsius were investigated by using a channel flow double electrode method. The enhanced ORR activities of the alloy electrodes are ascribed to increase in the preexponential factor in the Arrhenius equation, maybe relating to an increased O2 coverage.
