Guosong Zeng, a postdoctoral scholar, and Francesca Toma, a staff scientist, both in the Chemical Sciences Division of Lawrence Berkeley National Laboratory, test the artificial photosynthesis device developed by Zetian Mi, a professor of electrical and computer engineering at the University of Michigan. Rather than degrading over time, as is typical for devices that turn water and light into hydrogen fuel, this device improves. Image credit: Berkeley Lab
In a finding that could help make artificial photosynthesis a practical method for producing hydrogen fuel, researchers have discovered why a water-splitting device made with cheap and abundant materials unexpectedly becomes more efficient during use.
