Qualitative and Quantitative Mapping of a Pd-Pt Core Shell Particle
HAADF image of Pd-Pt core shell particles, the brightest one was analyzed in this application example
Core shell particles play an increasingly important role in nanotechnology, particularily in catalysis. This application example presents element maps of a Pd-Pt core shell nano-particle. The image gallery contains a HAADF image of the particle overlaid with a qualitative mixed element map of Pd and Pt. The quantitative single element maps provide an even clearer picture of the core-shell element distribution. It can also be seen that the particle contains no Pt on its left side, which is due to the production process. The data was kindly provided by Johnson Matthey and the University of Birmingham (UK).
