Solar fuels can be made by splitting water into H2 and O2 with the help of sunlight. Most photosynthetic organisms use a manganese-centered structure known as photosystem II for the O2 evolution portion of that process. But the most active synthetic mimics of that system break down quickly under catalytic conditions as the catalyst molecules react with one another to form a variety of inert species.
