2015 m. Nr. 3 Graphene and niobium(V) oxide/graphene supported platinum–cobalt catalysts as cathode material for oxygen reduction
The paper describes fabrication of the graphene and Nb2O5/graphene supported Pt or PtCo nanoparticles catalysts by means of microwave synthesis. The electrocatalytic activities of the synthesized catalysts towards the reduction of oxygen were investigated by linear scan voltammetry.
It has been found that the graphene and Nb2O5/graphene supported PtCo nanoparticles catalysts show exhibited electrocatalytic efficiency towards the reduction of oxygen when compared with that of bare Pt/GR catalyst. Keywords: platinum–cobalt, niobium(V) oxide, electrocatalysts, oxygen reduction |
