Three-dimensional atomic mapping of ligands on palladium nanoparticles by atom probe tomography

Abstract

Despite the important role of ligands in designing nanoparticles, directly imaging them on the nanoparticle surface remains a challenge. Here, the authors use atom probe tomography to map the spatial distribution of ligands on nanoparticles and reveal that the interplay between halide and cetrimonium ligands decides the oxidation resistance and shape of Pd nanoparticles.
