Watching a nanoscale catalyst generate oxygen (IMAGE)
Caption
An illustration shows bubbles of oxygen rising from the edges of a six-sided, plate-like catalyst particle, 200 times smaller than a red blood cell, as it carries out a reaction called OER that splits water molecules and generates oxygen gas. The small arm at left is from an atomic force microscope. It's one of a suite of techniques that researchers from SLAC, Stanford, Berkeley Lab and the University of Warwick brought together to study this reaction - a key step in producing clean hydrogen fuel - in unprecedented detail. The concentric rings represent the scanning transmission X-ray microscope's Fresnel zone plate used to image the process at Berkeley Lab's Advanced Light Source.
