DailyTech – MIT Scientist Claims Solar Breakthrough, Sparks Controversy

Daniel Nocera PhD, a professor of chemistry at MIT, devised a catalyst system using strips of cobalt, nickel, and phosphate, all relatively inexpensive chemical compounds.  By eschewing expensive catalysts like platinum, the cost of the system is kept low.  So why didn’t others think of this efficient system?  Well, he says that it is commonly known that cobalt dissolves relatively easy in water, making it typically a poor electrode material, and typically earning it a quick dismissal.  To remedy this, Professor Nocera chose a somewhat creative approach, instead adding dissolved cobalt directly to the solvent and relying on a thin cobalt film which formed on the electrode.
