First nanoscale look at a reaction that limits the efficiency of generating clean hydrogen fuel

his animation combines images of a tiny, plate-like catalyst particle as it carries out a reaction that splits water and generates oxygen gas – part of a clean, sustainable process for producing hydrogen fuel.

An international team of researchers from Stanford and the DOE's SLAC Laboratory developed a suite of advanced tools to break through the bottleneck of oxygen evolution reaction which today is only about 75% efficient and uses precious metal catalysts. These tools improve other energy-related processes such as finding ways to make lithium-ion batteries charge faster. Researchers will use the techniques developed toward other energy-related reactions such as fast charging in battery electrodes, carbon dioxide reduction for carbon capture and oxygen reduction to use hydrogen in fuel cells.
