Article Preview

The deposition of Pd nanoparticles onto thiol-functionalized SnO2 nanoparticles was carried out at the aqueous/organic liquid/liquid interface to prepare Pd-loaded SnO2 nanoparticles for high-sensitive sensor materials. The method is based on the self-assembly deposition of Pd onto dimercaptosucinic acid (DMSA)-functionalized SnO2 nanoparticles (mean diameter: 4 nm) prepared by a hydrothermal method. Pd nanoparticles of 2-3 nm in chloroform were prepared by thermal decomposition of a Pd complex at high temperature (170 °C). Thin film-type device using the prepared Pd-loaded SnO2 nanoparticles was fabricated and tested for its sensing properties.
