| Swedish researchers from the Royal Institute of Technology (KTH) have
built a molecular catalyser that can oxidize water to oxygen and protons
very quickly - reaching speeds not far off those of natural
photosynthesis.
While artificial photosynthesis has been under development for 30 years,
it is the first time that such a conversion rate has been reached -
about 300 turnovers per second, compared with 100 to 400 for natural
photosynthesis.
The result could make it possible in the future to create large-scale
facilities for producing hydrogen in the Sahara, or combine the
technique with traditional solar cells, according to the researchers.
The team plans to continue working to try and drive down the price of
the technology. |
