Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Oxygenophilic Cerium Promotes Active Species Generation and Modulates the Interfacial Water Network in Electrocatalytic Water Oxidation

Carbon Energy, EarlyView.
CeO2 dendrites are introduced to modify the NiSx/C3N4 nanorods, constructing hexagonal star‐like forest arrays (CeO2@NiSx/C3N4). The oxophilicity of Ce species generates abundant oxygen vacancies, which subsequently facilitate the in situ evolution of active amorphous NiOOH.

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Destinasjon Lom

, 2014
Gjennom denne oppgaven har vi undersøkt hvordan destinasjonen Lom fungerer per dags dato, og videre forsøkt å kartlegge hvor de ulike reiselivsaktørene selv mener potensialet for videreutvikling ligger. Som et utgangspunkt for vår oppgave valgte vi følgende problemstilling: Hva kan gjøres for å øke destinasjonens konkurransekraft?

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Dynamic Active Site Mechanism and Compositional Tuning in LaxSr1−xCoyFe1−yO3 (LSCF) Perovskites Toward Efficient Oxygen Evolution

EcoEnergy, EarlyView.
A dynamic active site mechanism through cooperative metal–lattice oxygen interactions enables efficient oxygen evolution in LSCF perovskites without relying on oxygen vacancy formation, where the La/Sr ratio governs the intrinsic activity of LSCF and Co incorporation provides secondary enhancement, establishing a general composition‐guided paradigm for
