Large area sub-100 nm direct nanoimprinting of palladium nanostructures

Abstract

We demonstrate a simple direct nanoimprinting method for fabricating palladium nanostructures that involves in situ free radical polymerization of a resin consisting of an acrylate-based crosslinker and a palladium metal precursor.

Effective Adsorption of Precious Metal Palladium over Polyethyleneimine-Functionalized Alumina Nanopowder and Its Reusability as a Catalyst for Energy and Environmental Applications

“…The deconvolution of the curve reveals that the palladium mostly exists in its +2 oxidation state when adsorbed over PEI-AO. After reduction, the peaks have become much sharper and shifted to a lower binding energy value, which substantiated that the Pd present in rPd-PEI-AO was successfully reduced to zero-valent oxidation state …”

“…After reduction, the peaks have become much sharper and shifted to a lower binding energy value, which substantiated that the Pd present in rPd-PEI-AO was successfully reduced to zero-valent oxidation state. 49 X-ray diffraction (XRD) patterns were recorded for pristine AO, Pd-PEI-AO, and rPd-PEI-AO and presented in Figure 8. The pristine AO exhibited broad peaks, indicating the amorphous nature of alumina possessing a certain amount of nanocrystalline domains.…”
