Hydrogen evolution by photobleached Anabaena cylindrica
Planta, 1981We have studied the evolution of hydrogen by photobleached filaments of the heterocystous bluegreen alga Anabaena cylindrica. The photobleached cells became orange-yellow due to the heavy accumulation of carotenoids. We found that the yellow filaments produced much larger amounts of hydrogen than the normal, green ones, while the nitrogenase activity ...

Hydrogen evolution: Guiding principles
Nature Energy, 2016Lower-cost alternatives to platinum electrocatalysts are being explored for the sustainable production of hydrogen, but often trial-and-error approaches are used for their development. Now, principles are elucidated that suggest pathways to rationally design efficient metal-free electrocatalysts based on doped graphene.

Semisynthetic and Biomolecular Hydrogen Evolution Catalysts
Inorganic Chemistry, 2015There has been great interest in the development of stable, inexpensive, efficient catalysts capable of reducing aqueous protons to hydrogen (H2), an alternative to fossil fuels. While synthetic H2 evolution catalysts have been in development for decades, recently there has been great progress in engineering biomolecular catalysts and assemblies of ...

The Photosynthetic Unit of Hydrogen Evolution
Science, 1977A study of the absolute photoproduction of hydrogen by autotrophically grown Chlorella vulgaris with single-turnover flashes of light indicates that (i) while the Emerson and Arnold photosynthetic unit has the value chlorophyll : oxygen ≈ 1700 : 1, the hydrogen analog of this unit has the value chlorophyll ...

2009
The article begins with a brief presentation of the strategic importance of the hydrogen evolution reaction in various fields; this is followed by a discussion of its reversibility and of the factors on which reversibility depends. Adsorption of hydrogen atoms is a necessary step that depends on the interaction of metal surfaces with solvents.

Organocatalytic Hydrogen Evolution Reaction by Diazaphospholenes
Journal of the American Chemical SocietyThe electrochemical hydrogen evolution reaction (HER) is currently recognized as a prospective way to obtain clean energy. The electrocatalysts used currently are dominantly based on transition metals. In this work, we have demonstrated a diazaphospholene (N-heterocyclic phosphine (NHP))-type small molecular organocatalyst that can catalyze the HER ...
