TEM images of catalyst

Caption

High-resolution electron microscopy images of the catalyst captured at the CFN. Frame A shows the catalyst with a scale bar representing 20 nanometers (nm) after three consecutive reaction cycles; B zooms in to reveal surface details; C provides a composite elemental map, with individual elements shown in D, E, and F. Together the images reveal that the active metal, palladium (Pd), is highly dispersed on the supporting cerium (Ce) substrate with a thin layer of carbon (C) at the interface.
