Magnesium Hydrogen-generating Materials and a Hydrogen Generation Setup

Russian Journal of Applied Chemistry, 2023
The reaction of composites consisting of MgH2 and a graphene-like or nickel–graphene material with water or citric acid solutions of various concentrations was studied. The composites were prepared by mechanochemical treatment in a hydrogen atmosphere.

Disposable Hydrogen Generator

Science, 1965
A convenient means of producing hydrogen gas for anaerobe jars or other situations where 2 liters of hydrogen will suffice is described. Hydrogen gas is produced by the chemical action of magnesium metal, zinc chloride, sodium chloride, and water within a unique plastic and aluminum foil envelope.

Hydrogen-cooled turbine generators

Electrical Engineering, 1940
ONE of the most radical innovations in the design of electrical machinery in recent years has been the adoption of hydrogen cooling for large turbine generators. Now that a number of the large hydrogen-cooled units are in operation, it would seem timely to review the experience gained in building and operating this new-type equipment.

Thermochemical Hydrogen Generation

Science, 1974
The basic concepts for thermochemical hydrogen generation processes have been summarized in this article. A useful set of criteria has been described for the screening and selection of potentially viable, multistep, closedcycle thermochemical processes for hydrogen generation.

Bimetallic catalysts for hydrogen generation

Chemical Society Reviews, 2012
Research interest in bimetallic catalysts is mainly due to their tunable chemical/physical properties by a number of parameters like composition and morphostructure. In catalysis, numerous bimetallic catalysts have been shown to exhibit unique properties which are distinct from those of their monometallic counterparts. To meet the growing energy demand

Photovoltaic hydrogen generation

International Journal of Hydrogen Energy, 2008
Fuel production via light generated electricity and water splitting is a fundamental quantum solar energy conversion process, which is also applied in nature and, thus, via fossil fuel and biomass, responsible for most of our present energy supply. Significant advantages of this technology are elegant energy conversion mechanisms, applicability at ...

Hydrogen Generation by Hangman Metalloporphyrins

Journal of the American Chemical Society, 2011
A cobalt(II) hangman porphyrin with a xanthene backbone and a carboxylic acid hanging group catalyzes the electrochemical production of hydrogen from benzoic and tosic acid in acetonitrile solutions. We show that Co(II)H is exclusively involved in the generation of H(2) from weak acids.
