Hydrogen Spillover in Electrochemical Hydrogen Evolution Reaction

General Chemistry, 2022
The dissociative chemisorption and energetically driven migration of atomic hydrogen on heterogenous electrocatalysts, i.e., hydrogen spillovers, which occur during electrochemical turnovers, have been intensively investigated recently on high-performance electrocatalysts for hydrogen evolution reaction.

Intercepting Hydrogen Evolution with Hydrogen-Atom Transfer: Electron-Initiated Hydrofunctionalization of Alkenes [PDF]

, 2022
Hydrogen-atom transfer mediated by earth-abundant transition-metal hydrides (M-Hs) has emerged as a powerful tool in organic synthesis. Current methods to generate M-Hs most frequently rely on oxidatively initiated hydride transfer.

Hydrogen symbioses in evolution and disease [PDF]

QJM, 2007
Hydrogen is the source of energy that unites the metabolisms and fuels the innovative potentials of all living organisms. Autotrophs use hydrogen emitted into hydrothermal vents, where symbiotic communities that share hydrogen thrive. On the surface, life developed using photons to cleave water, releasing hydrogen carried into a reverse Krebs cycle to ...

Hydrogen Evolution by Trichomonas fœtus [PDF]

Nature, 1951
Trichomonas fœtus, a polyflagellated protozoon, is parasitic in the vagina of the cow and causes impaired reproduction. J. Andrews and T. von Brand1 carried out some quantitative studies on glucose consumption by T. fœtus during cultivation, and then also found that a gas, which burned explosively when mixed with air, was produced by the organism when ...

Quantification of photocatalytic hydrogen evolution [PDF]

Physical Chemistry Chemical Physics, 2013
A new photoreactor with defined irradiation geometry was developed and tested for the water reduction reaction using carbon nitride (“C3N4”) as a photocatalyst. The hydrogen evolution rate was investigated with a sun simulator (I = 1000 W m−2) in two different operation modes: circulation and stirring of the catalyst dispersion.

Study on Thermal Effect of Aluminum-Air Battery

Nanomaterials, 2023
The heat released from an aluminum-air battery has a great effect on its performance and operating life during the discharge process. A theoretical model was proposed to evaluate the resulting thermal effect, and the generated heat was divided into the ...

Weyl Semimetals as Hydrogen Evolution Catalysts [PDF]

Advanced Materials, 2017
The search for highly efficient and low‐cost catalysts is one of the main driving forces in catalytic chemistry. Current strategies for the catalyst design focus on increasing the number and activity of local catalytic sites, such as the edge sites of molybdenum disulfides in the hydrogen evolution reaction (HER).

Hydrogen Evolution at Liquid–Liquid Interfaces [PDF]

Angewandte Chemie International Edition, 2009
AbstractBlowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2‐dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequent proton reduction in DCE.
