Researchers have used sunlight to convert carbon dioxide and water vapour into a range of fuels faster than ever before, thanks to a nanotube catalyst.

Materials scientist Craig Grimes and his colleagues at Pennsylvania State University in University Park have used hollow titania (titanium dioxide) nanotubes around 135 nanometres wide and a tenth of a millimetre long to catalyse the reaction. Scientists have used titania nanoparticles to speed up this process before, but Grimes and his colleagues were able to generate hydrocarbons around 20 times faster than that achieved in previous studies, thanks to some clever chemistry.
