【 摘 要 】

Nano-beam electron diffraction (NBD) has been used in addition to HAADF-STEM and HRTEM analyses of Pd-Al2O3and Pt-Al2O3catalysts. 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 (
