| Popis: | The purpose of this paper was to investigate the influence of fabrication conditions of the carbon based cobalt(II, III) oxide (Co3O4/C) and Au supported Co3O4/C (AuCo3O4/C) catalysts on their electrocatalytic activities towards the oxygen reduction reaction (ORR). The catalysts were prepared using impregnation and microwave irradiation methods. It has been found, that the combination of both of these methods was a more efficient way for fabrication of high catalytically active Co3O4/C and AuCo3O4/C catalysts. The synthesized Co3O4/C and AuCo3O4/C catalysts showed high electrocatalytic activity towards the oxygen reduction reaction in an alkaline medium. The ORR onset potential for the investigated catalysts was comparable to theoretical ORR potential values between 0.7 and 0.9 V vs. reversible hydrogen electrode (RHE). |
