Mechanisms of hydrogen evolution on chromium [PDF]

Mining and Metallurgy Engineering Bor, 2015
In this work, the mechanisms of hydrogen evolution on the metal chromium in a solution of 0.1 M Na2SO4 + H2SO4, pH 1 to pH 7 were analysed. In the pH < 3 range, hydrogen is evolved according to three different mechanisms, depending on the experimental ...

Dynamic restructuring of nickel sulfides for electrocatalytic hydrogen evolution reaction

Nature Communications
Transition metal chalcogenides have been identified as low-cost and efficient electrocatalysts to promote the hydrogen evolution reaction in alkaline media. However, the identification of active sites and the underlying catalytic mechanism remain elusive.

Strategies and Perspectives to Catch the Missing Pieces in Energy‐Efficient Hydrogen Evolution Reaction in Alkaline Media

Angewandte Chemie, 2021
Transition metal hydroxides (M‐OH) and their heterostructures (X|M‐OH, where X can be a metal, metal oxide, metal chalcogenide, metal phosphide, etc.) have recently emerged as highly active electrocatalysts for hydrogen evolution reaction (HER) of ...

Surfactant-Mediated Interfacial Hydrogen Evolution Reaction

ACS Applied Materials & Interfaces
Hydrogen is a highly promising clean energy source without greenhouse gas emissions. Liquid organic hydrogen carriers (LOHCs) offer a promising alternative for convenient storage and transportation. This study investigates the interfacial hydrogen evolution reaction between polymethylhydrosiloxane (PMH), a representative LOHC, and water, focusing on ...

Minimal‐power control of hydrogen evolution reactions

Optimal Control Applications and Methods, 2009
AbstractAn integral approach to solve finite‐horizon optimal control problems posed by set‐point changes in electrochemical hydrogen reactions is developed. The methodology extends to nonlinear problems with regular, convex Hamiltonians that cannot be explicitly minimized, i.e.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...
