Abstract
Influence of temperature on the oxygen reduction kinetics of various catalysts has been analyzed in O2 saturated 0.1M KOH solution using rotating disc electrode method. Several important reaction parameters, such as the number of electrons transferred per one oxygen molecule, the slope values of Tafel-like plots at different temperatures, and the apparent activation energies for the oxygen reduction reaction were obtained. The calculated absolute kinetic current density value (62.6 A m-2) at the half-wave potential (-0.05V vs. HgêHgOê0.1M KOH) of platinum nanoparticles modified catalyst was maximum at 60oC. Calculated apparent activation energies were within a range from 19 to 27 kJ mol-1 at Pt nanoparticles modified molybdenum carbide derived carbon catalyst within potential range from 0.05 to -0.07V vs. HgêHgOê0.1M KOH.
