Non‐Fermi Liquids as Highly Active Oxygen Evolution Reaction Catalysts
The oxygen evolution reaction (OER) plays a key role in emerging energy conversion technologies such as rechargeable metal-air batteries, and direct solar water splitting. Herein, a remarkably low overpotential of ≈150 mV at 10 mA cm-2disk in alkaline solutions using one of the non-Fermi liquids, Hg2Ru2O7, is reported. Hg2Ru2O7 displays a rapid increase in current density and excellent durabili...
متن کاملElectrocatalytic Oxygen Evolution Reaction in Acidic Environments Reaction Mechanisms and Catalysts
DOI: 10.1002/aenm.201601275 order to bridge the time gap between supply and demand. Molecular fuels like hydrogen or hydrocarbons produced from renewable electricity and water or CO2, respectively, can provide such a longterm chemical energy storage solution.[1–3] Considering hydrogen, its reconversion to electrical energy can be efficiently performed in fuel cells.[4] In a transition period, h...
متن کاملBeyond 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...
متن کاملNickel Oxide/Carbon Nanotubes as Active Hybrid Material for Oxygen Evolution Reaction
Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT were investigated by using scanning electron microscope (SEM) and energydispersive X-...
