Design of NiFe‐based nanostructures for efficient oxygen evolution electrocatalysis

Highly branched cobalt phosphide nanostructures for hydrogen-evolution electrocatalysis

CoP nanostructures that exposed predominantly (111) crystal facets were synthesized and evaluated for performance as electrocatalysts for the hydrogen-evolution reaction (HER). The branched CoP nanostructures were synthesized by reacting cobalt(II) acetylacetonate with trioctylphosphine in the presence of trioctylphosphine oxide. Electrodes comprised of the branched CoP nanostructures deposited...

Beyond the volcano limitations in electrocatalysis--oxygen evolution reaction.

Oxygen evolution catalysis is restricted by the interdependence of adsorption energies of the reaction intermediates and the surface reactivity. The interdependence reduces the number of degrees of freedom available for catalyst optimization. Here it is demonstrated that this limitation can be removed by active site modification. This can be achieved on ruthenia by incorporation of Ni or Co int...

Oxygen Evolution Reaction Electrocatalysis on Transition Metal Oxides and (Oxy)hydroxides: Activity Trends and Design Principles

Poor oxygen evolution reaction (OER) catalysis limits the efficiency of H2 production from water electrolysis and photoelectrolysis routes to large-scale energy storage. Despite nearly a century of research, the factors governing the activity of OER catalysts are not well understood. In this Perspective, we discuss recent advances in understanding the OER in alkaline media for earth-abundant, f...

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...
