Promising news for solar fuels from Berkeley Lab researchers at JCAP
Date:3/7/2014

There's promising news from the front on efforts to produce fuels through artificial photosynthesis. A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90-percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.

Gary Moore, a chemist and principal investigator with Berkeley Lab's Physical Biosciences Division, led an efficiency analysis study of a unique photocathode material he and his research group have developed for catalyzing the production of hydrogen fuel from sunlight. This material, a hybrid formed from interfacing the semiconductor gallium phosphide with a molecular hydrogen-producing cobaloxime catalyst, has the potential to address one of the major challenges in the use of artificial photosynthesis to make renewable solar fuels.

"Ultimately the renewable energy problem is really a storage problem," Moore says. "Given the intermittent availability of sunlight, we need a way of using the sun all night long. Storing solar energy in the chemical bonds of a fuel also provides the large power densities that are essential to modern transport systems. We've shown that our approach of coupling the absorption of visible light with the production of hydrogen in a single material puts photoexcited electrons where we need them to be, stored in chemical bonds."

Moore is the corresponding author of a paper describing this research in the journal Physical Chemistry Chemical Physics titled "Energetics and efficiency analysis of a cobaloxime-modified semiconductor under simulated air mass 1.5 illumination." Co-authors are Alexandra Krawicz and Diana Cedeno.

Bionic leaves that produce energy-dense fuels from nothing more than sunlight, water and atmosphere-warming carbon dioxide, with no byproducts other than oxygen, represent an ideal sustainable energy alternative to f
