Nano-beam electron diffraction (NBD) has been used in addition to HAADF-STEM and HRTEM analyses of Pd-Al 2 O 3 and Pt-Al 2 O 3 catalysts. NBD and its STEM nanodiffraction counterpart are not widely used for nanoparticle catalysts but the more common SAD method does not offer the same level of structural information for individual ultrafine (< 10 nm) nanoparticles, even with aberration correction. Here, NBD has been applied to commercially relevant catalysts for added information and to
