Title: Surface softening in palladium nanoparticles: effects of a capping agent on vibrational properties

Journal Article · · Nanoscale
DOI: https://doi.org/10.1039/d0nr00182a · OSTI ID:1633058

The presence of a capping agent (CTAB) on Pd nanoparticles produces a strong static disorder in the surface region. This results in a surface softening, which contributes to an overall increase in the Debye–Waller coefficient measured by X-ray powder diffraction. Here, molecular dynamics and density functional theory simulations show that the adsorption-induced surface disorder is strong enough to overcome the effects of nanoparticle size and shape.
