Scientists at the Energy Department’s National Renewable Energy Laboratory (NREL) announced advances have been made toward affordable photoelectrochemical (PEC) production of hydrogen. PEC is solar energy driving a semiconductor coated with a catalyst that for this example chemically splits hydrogen from water. The NREL work shows that molecular catalysts can be as highly active as […]

University of Oregon (UO) scientists developed a new method called “dual-electrode photoelectrochemistry” to gain a new insight into the chemistry of splitting water.  Their first result is an important and overlooked parameter, the ion-permeability of electrocatalysts used in water-splitting devices. Shannon W. Boettcher, professor of chemistry and head of the Solar Materials and Electrochemistry Laboratory […]

Getting solar energy into a stored form is a major and elusive goal.  One idea that has intrigued for decades is using solar energy to split water for the hydrogen product.  Some wee progress has been made.  May 10, 2011 saw a Swiss Ecole Polytechnique Fédérale de Lausanne (EPFL) team discovering that it is possible […]
