Abstract

Hydrogen and oxygen titration experiments have been performed for Au nanoparticles embedded in yttria-stabilized zirconia (Au-YSZ) nanocomposites at 500 °C and characteristic localized surface plasmon resonance (LSPR) absorption data has been acquired of the LSPR band in a variety of gas exposures. A model has been developed which attributes peak position shift to charge exchange between the gas environment and the nanocomposite. Using the calculated charge exchange, number of chemisorbed and incorporated oxygen ions, a qualitative description for the mechanisms dictating the broadening of the LSPR band have been made and the trend of the experimental data leads to the conclusion that the filled oxygen ion vacancies within the YSZ matrix for the Au-YSZ nanocomposite used in this study are at the Au nanoparticle/YSZ interface.)
