Cyclodextrin inclusion compound crystals for growth of Cu-Au core-shell nanoparticles
MetadataShow full item record
The preparation and structural elucidation of the 2 alpha-cyclodextrin/decylamine inclusion compound (IC) by proton nuclear magnetic resonance, rotating frame overhauser effect spectroscopy and powder X-ray diffraction have been achieved. The IC microcrystals were used as a support for the preparation of Au-Cu core-shell nanoparticles by the sputtering method. The coating of copper nanoparticles with gold was verified through anodic stripping voltammetry. The presence of metallic copper and the absence of copper oxides were determined by X-ray photoelectron spectroscopy. These results show that the formation of core-shell Cu-Au by sputtering is an effective approach to prevent the oxidation of Cu particles, leading to potential applications in nanoelectronics.
