ECS’s Nate Lewis is propelling his vision of efficient and affordable alternative energy sources with the new development of an “artificial leaf” system that splits water through solar energy to create hydrogen fuel.
(PS: Make sure to catch Nate Lewis’ presentation this October at the fifth international Electrochemical Energy Summit held during the 228th ECS Meeting!)
“This new system shatters all of the combined safety, performance, and stability records for artificial leaf technology by factors of 5 to 10 or more,” says Lewis, a 33-year ECS member and scientific director of the Joint Center for Artificial Photosynthesis.
Shattering Water Splitting Records
He and his team, including postdoctoral scholar and ECS member Ke Sun, were able to achieve recording-setting outcomes through the development of a advice with three novel components: two electrodes, one photoanode and one photocathode, and a membrane.
This from Futurity:
The photoanode uses sunlight to oxidize water molecules, generating protons and electrons as well as oxygen gas. The photocathode recombines the protons and electrons to form hydrogen gas.
