Using a semiconductor as a photocatalyst for solar hydrogen production
While other semiconductors have been tested, titanium disilicide has the ability to absorb light over more of the spectrum. This provides for greater efficiency in splitting the hydrogen. At the same time that the water molecules are split, the hydrogen and oxygen molecules are absorbed separately. The oxygen and hydrogen can be released by separate processes and captured individually. The researchers have now started a company in Lörrach, Germany to develop and commercialize the techonology.
