Towards a More Accurate Particle Size Distribution of Supported Catalyst by using HAADF‐STEM

STEM can make a large difference: Conventionally the catalysis community has used HRTEM (figure, left) imaging to obtain the particle size distribution (PSD) of supported catalysts. Now we have found that by using the analogous HAADF-STEM (figure, right) a more accurate PSD can be calculated, which is crucial for understanding the catalysis mechanisms.
