LIGHT TURNS C[O.sub.2] INTO FUEL.

Researchers in South Korea have developed a photocatalyst that can turn carbon dioxide from the atmosphere into hydrocarbon fuels. A group from the Daegu Gyeongbuk Institute of Science and Technology worked with colleagues in Japan and the US to modify a blue titania photocatalyst by adding nanoparticles of copper, which is good at absorbing C[O.sub.2], and platinum, which is good at separating the charges generated by the blue titania from the sun's energy.

The group have reached an important milestone and were able to convert sunlight into fuel with an efficiency of 3.3% over 30 minutes, according to research published in the journal Energy & Environmental Science.

"The photocatalyst has a very high conversion efficiency and is relatively easy to manufacture, making it advantageous for commercialisation," said lead researcher Professor Su-Il In.
