Tony Chan, assistant director for NSF's Directorate for Mathematical & Physical Sciences, tells us why the new oxygen catalyst technique is what NSF is all about. This research produces a significant impact on society in one of our most important problems, sustainable energy.
Luis Echegoyen, director of NSF's Division of Chemistry, describes how the researchers achieved the holy grail of science, producing oxygen from water, a notoriously slow reaction. The experiment is simple and can be done in your kitchen sink. Just apply a electric potential in a neutral pH salty water solution. A thin film is produced on the surface of the catalyst that forms oxygen from water. The reaction is made truly accessible.

View video MIT's Matthew W. Kanan and Daniel G. Nocera explain how they recently discovered a catalyst that produces oxygen gas from water. Deposited on a conducting glass electrode, the catalyst made from the earth-abundant materials cobalt and phosphate produces oxygen gas from neutral pH water using a relatively low potential at room temperature and pressure. Although the catalytic reaction is not yet fully understood, its discovery moves the center one step closer to reaching its goal of using the sun's energy and water as a renewable energy source.
