Kinetics and mechanism of oxygen electroreduction on PtCoCr/C catalyst containing 20–40 wt % platinum
Autor: V. A. Bogdanovskaya, M. R. Tarasevich, O. V. Lozovaya
Publikováno v: Russian Journal of Electrochemistry. 47:846-860
It is shown that the mechanism of oxygen electroreduction on the PtCoCr/C systems in 0.5 M H2SO4 is similar to that proposed for the Pt/C catalyst. The activity of ternary catalysts is by two and more times higher than that of monoplatinum catalyst.

Autor: I. Yu. Pinus, V. A. Bogdanovskaya, O. V. Lozovaya, A. Yu. Tsivadze, M. R. Tarasevich
Publikováno v: Doklady Physical Chemistry. 438:86-89
Cathode catalysts used at present in fuel cells (FC) are disperse monoplatinum systems on carbon sup� ports, Pt/C. These systems have many disadvantages, including high cost and low corrosion stability (1). Moreover, platinum can catalyze carbon ox

Publikováno v: Russian Journal of Electrochemistry. 46:925-933
Bimetallic catalysts PtM (M = Co, Ni, or Cr) are synthesized. They exceed purely platinum commercial catalyst E-TEK (20 wt % Pt) in its mass activity (mA/mgPt) and specific activity (mA/cPt2) in the oxygen reduction reaction. According to XRD data, t
