Artificial leaf jumps developmental hurdle


R&D – Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel—the Energy Frontier Research Center, funded by the U.S. Dept. of Energy, in the Dept. of Chemistry and Biochemistry at Arizona State Univ.

“We looked in detail and found that nature had used an intermediate step,” said ASU chemistry prof. Thomas Moore. “This intermediate step involved a relay for electrons in which one half of the relay interacted with the fast step in an optimal way to satisfy it, and the other half of the relay then had time to do the slow step of water oxidation in an efficient way.” more> http://tinyurl.com/lm8fjh6
