"Our titanium oxide one-dimensional nanofilaments photocatalyst showed activity that is substantially higher - by an order of magnitude - than its commercial titanium oxide counterpart," Hussein said. Their article "Photo-stable, 1D-nanofilaments TiO2-based lepidocrocite for photocatalytic hydrogen production in water-methanol mixtures," published in the journal Matter, presents a sustainable and affordable path for creating hydrogen fuel, according to the authors. Badr, PhD, in collaboration with scientists from the National Institute of Materials Physics in Bucharest, Romania, recently reported its discovery of photocatalytic titanium oxide-based, one-dimensional nanofilament material that can help sunlight glean hydrogen from water for months at a time. Photocatalysis, a process that can split hydrogen from water using only sunlight, has been explored for several decades, but has remained a more distant consideration because the catalyst materials enabling the process can only survive it for a day or two, which limits its long-term efficiency and, as a result, its commercial viability.ĭrexel's group, led by College of Engineering researchers Michel Barsoum, PhD, and Hussein O. The discovery offers an alternative to current methods that generate greenhouse gas and require a great deal of energy.
