Pioneering new tool will spur advances in catalysis

Researchers from the U.S. Department of Energy's SLAC National Accelerator Laboratory, Stanford University, and the University of California, Davis, have developed a new software tool that can provide more quantitative details about the structure of the active sites in single atom catalysts in much less time, compared to current methods. Normally, a catalyst uses an inert support to stabilize nanometer-sized clusters of metal atoms, or metal nanoparticles. To maximize the use of each metal atom, researchers also use single atom catalysts, where individual metal atoms are dispersed onto the support. In reality, catalysts usually have both single atoms and nanoparticles, and the new software tool determines the fractions of these two forms.
