Electron Micrograph and Atomistic Model of a Highly Oxygen-Activating Platinum-Nickel

Caption

This is an electron micrograph and atomistic model (bottom right) of a highly oxygen-activating platinum-nickel catalyst particle. Its diameter is approximately 10,000 times smaller than the diameter of a human hair. Red spheres represent platinum atoms and green spheres represent nickel atoms. One of the properties of such octahedra is that most surface atoms have the same geometric arrangement. The micrograph was taken at the PICO microscope.
