PY - 2018 DA - 2018/02/20 TI - Differentiating the structure of PtNi octahedral nanoparticles through combined ADF–EDX simulations JO - Advanced Structural and Chemical Imaging SP - 2 VL - 4 IS - 1 AB - Advances in catalysis rely on the synthesis and characterisation of nanoparticles that have tailored structures and compositions. Although energy-dispersive X-ray (EDX) spectroscopy can be used to study local variations in the compositions of individual supported nanoparticles on the atomic-scale in the scanning transmission electron microscope, electron beam induced damage and contamination can preclude the use of long exposure times and tomographic approaches. Here, we perform simulations of EDX maps of seven different octahedral PtNi nanoparticles for a selection of crystallographic orientations and tilts, to evaluate which of them can be distinguished from elemental mapping performed in only one orientation.
