Operando identification of a side-on nickel superoxide intermediate and the mechanism of oxygen evolution on nickel oxyhydroxide
Xile Hu, Lichen Bai, Seunghwa Lee
The oxygen evolution reaction (OER) is a key electrochemical reac-tion relevant to energy storage. Ni-containing bimetallic oxyhydrox-ides are among the most active OER catalysts in alkaline medium, but the mechanism of OER on pure Ni oxyhydroxide remains ...
ELSEVIER2023Evidence that Pacific tuna mercury levels are driven by marine methylmercury production and anthropogenic inputs
Pacific Ocean tuna is among the most-consumed seafood products but contains relatively high levels of the neurotoxin methylmercury. Limited observations suggest tuna mercury levels vary in space and time, yet the drivers are not well understood. Here, we m ...
National Academy of Sciences2022Print-Light-Synthesis of Ni and NiFe-nanoscale catalysts for oxygen evolution
Hubert Girault, Emad Oveisi, Mounir Driss Mensi, Andreas Stephan Lesch, Victor Costa Bassetto
By hyphenating inkjet printing and flash light irradiation, Ni- and NiFe-nano-electrocatalysts of diameters below 2.5 nm with ultralow loadings below 2 µg·cm–2 are synthesized. To achieve this, nanoliter ink volumes containing Ni and Fe chlorides as cataly ...
2019IrOOH nanosheets as acid stable electrocatalysts for the oxygen evolution reaction
In solids, heterogeneous catalysis is inherently bound to reactions on the surface. Yet, atomically efficient preparation of specific surfaces and the characterization of their properties are impeding its applications towards a clean energy future. Here, w ...
