Turning water and sunlight into fuel

摘要

Two American researchers have found a more efficient way of splitting water into hydrogen and oxygen gas using solar energy. If such a process can be performed efficiently on a large scale, it could be the ultimate clean energy source. Giulia Galli from the University of Chicago's Institute for Molecular Engineering and Kyoung-Shin Choi from the University of Wisconsin, Madison found a way to increase the efficiency with which an electrode used for splitting water absorbs solar photons, while at the same time improving the flow of electrons from one electrode to another.
