Electrocatalytic Oxygen Reduction Reaction

Oxygen (O2) is the most abundant element in the Earth’s crust. The oxygen reduction reaction (ORR) is also the most important reaction in life processes such as biological respiration, and in energy converting systems such as fuel cells. ORR in aqueous solutions occurs mainly by two pathways: the direct 4-electron reduction pathway from O2 to H2O, and the 2-electron reduction pathway from O2 to...

Electrocatalytic properties of platinum and it's binary alloy with vanadium in oxygen reduction reaction(ORR)

The electrocatalysis of the oxygen reduction reaction (ORR) on carbon supportedPt-V (1:1) catalyst in polymer electrolyte fuel cells (PEFC) was investigated. Atan oxygen pressure of one atm an enhanced electrocatalytic property of Pt-V/Ccompared with Pt/C is revealed. These results indicate the occurrence of adifferent electrocatalytic mechanism for the ORR on Pt/C and Pt-V/C. Anincrease of mas...

Oxygen-induced changes to selectivity-determining steps in electrocatalytic CO2 reduction.

The state of the electrocatalyst surface-including the oxidation state of the catalyst and the presence of spectator species-is investigated on Cu surfaces with density functional theory in order to understand predicted ramifications on the selectivity and efficiency of CO2 reduction. We examined the presence of oxygen-based species, including the fully oxidized Cu2O surface, the partially oxid...

Multifunctional graphene-based nanostructures for efficient electrocatalytic reduction of oxygen

Graphene derivatives have been used extensively as a functional support for nanoparticle catalysts in diverse applications, in particular, oxygen reduction reactions (ORR) at fuel cell cathodes. This review summarizes recent progress in this area of research, where the catalytic performance is evaluated within the context of stabilization of metal nanoparticles against sintering/aggregation and...
