"It seems that nanotube geometry is the best geometry for production of hydrogen from photolysis of water," says Grimes
In Grimes' photoelectrochemical diode, one side is a ...

... Hydrogen will be one of the most important fuels of the future. It would be ideal to obtain hydrogen by splitting water instead of from petroleum. However, the electrolysis of water is a very energy ...
... "green" technology developed cooperatively by scientists with the Agricultural Research Service and North Carolina State University could lead to production of hydrogen from nitrogen-fixing bacteria.
... month reached a major milestone with the successful production of hydrogen through High-Temperature Electrolysis ... Laboratory Scale experiment started producing hydrogen at a rate of 5.6 cubic meters ...
... can be hazardous.
Chemists have searched nearly a century for a catalyst that can directly combine hydrogen and oxygen to produce H2O2. They have had some luck with palladium, says Kiely, but their ...
... in the decades-long effort to produce H2O2 directly from oxygen and hydrogen and to limit its decomposition after production. A gold-palladium catalyst, placed on a carbon support pretreated with ...
... new mutant strains to help us understand how we may be able to alter fermentation metabolism and the production of hydrogen. NREL's Michael Seibert, the project's Principal Investigator, observed that ...
... or inject them with the drug," he said, because those effects will not be rhythmic, whereas production of hydrogen peroxide by the mitochondria and by SOD is expected to be rhythmic and to correspond ...
... that they do not generate contaminant gases, except water vapour as the only waste product. However, hydrogen is very expensive, both in producing it and in distributing it using traditional overland ...
... enzymes the cyanobacteria uses in this process is sensitive to O2, which makes sustained hydrogen production extremely difficult.
Luckily a certain purple bacterium use a similar hydrogenase, but ...
