Dynamic Surface Chemistry of Catalysts in Oxygen Evolution Reaction

چکیده
Dynamic Surface Chemistry of Catalysts surface chemistry controls the oxygen evolution reaction (OER) under a given set electrocatalytic servicing conditions. In article number 2100011, Zongkui Kou, Xin Li, Xiaorui Gao, John Wang, and co-workers review two competing processes, reversible irreversible reconstruction, where balance is affected by both pre-catalyst internal externally applied field factors. To develop efficient durable electrocatalysts for OER, real-time in-situ operando techniques, with multiscale computational studies are discussed.

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...

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 کاملOxygen evolution reaction electrocatalyzed on a Fenton-treated gold surface.
Hydroxyl radicals arising from the Fenton reagent remove metastable surface gold atoms (low coordinated high-energy surface atoms) on the Au surface, thus precluding the formation of stable oxides. The resultant smooth surface, upon hydroxyl-radical activation, electrocatalyzes oxygen evolution reaction in 0.1 M NaOH at overpotentials lowered by 190 mV @ 10 mA cm(-2).
متن کاملEvolution of dynamic combinatorial chemistry.
Since its inception in the mid-1990s, dynamic combinatorial chemistry (DCC), the chemistry of complex systems under thermodynamic control, has proved valuable in identifying unexpected molecules with remarkable binding properties and in providing effective synthetic routes to complex species. Essentially, in this approach, one designs the experiment rather than the molecule. DCC has also provid...
