Popis výsledku v původním jazyce
Oxygen reduction electrocatalysts based on the monoethanolmine complexes {[CoEtm](2)(mu-Etm)(4)Ni(NO3)(2)} and {[CoEtm](2)(mu-Etm)(4)Ni(NO3)(2)} + activated carbon AG-3 have been obtained by high-temperature synthesis. The nature of active centers on thesynthesized electrocatalysts was described. Using potentiostatic and cyclic potentiodynamic voltammetry, the kinetic characteristics of catalysts in the oxygen electroreduction reaction were determined. Thermal decomposition of the thermally unstable complexes was described and character of the active centers formed was discussed. The optimal synthesis temperature of electrocatalysts is 600 degrees C in an inert atmosphere. The calculated exchange current densities for the oxygen electroreduction reaction at the catalysts in 1 M KOH at 20 degrees C was j(0) = 1.01 x 10(-3) A g(-1) -3.3 x 10(-3) A g(-1). The Tafel slopes of stationary polarization curves are 0.054-0.063 V for b(1) and 0.106-0.125 V for b(2). The prepared electrocatalyst
