Through hydrogen reduction of metal precursors in supercritical CO2, Cu and Pd nanocrystals were deposited onto SiO2 nanowires (NWs) to form different types of nanostructured materials, including nanocrystal-NW, spherical aggregation-NW, shell-NW composites and “mesoporous” metals supported by the framework of NWs. This supercritical fluid deposition technique represents an attractive approach for modifying NWs because of its generality and simplicity and the modified NWs could be potentially useful as catalysts and for further fabrication of multifunctional composites.
