Water oxidation advance boosts potential for solar fuel

Bubbles form during water oxidation, catalyzed by a new tetra-cobalt water oxidation catalyst. The new catalyst, the most effective catalyst so far for water oxidation -- a crucial component in generating hydrogen fuel from water -- was developed by researchers in the lab of Emory University professor of chemistry Craig Hill.

More about this image
The water oxidation catalyst research is a component of the Emory Bio-inspired Renewable Energy Center (EBREC), which aims to mimic natural processes such as photosynthesis to generate clean fuel. The long-term goal is to use sunlight to split water into oxygen and hydrogen. Hydrogen becomes the fuel. Its combustion produces the byproduct of water, which flows back into a clean, green, renewable cycle.
