• Resumen

  • The article reports that nanotubes that break water molecules to liberate hydrogen now do so more efficiently, and could soon use the optical spectrum of sunlight. Engineers can use sunlight to dissociate water using photocatalysis. It relies on electrons freed momentarily in a semiconductor. However, photocatalysts must work in water and respond only to ultraviolet light. Scientists have made nanotubes of titanium dioxide to make the process efficient. They are working on producing a nanotube material that has high efficiency in pure visible light.
