Development and characterization of Au-YSZ surface plasmon resonance based sensing materials: High temperature detection of CO
Article Abstract:
The yttria-stabilized zirconia (Au-YSZ) nanocomposite films have displayed a surface plasmon resonance absorption band at around 600 nm, which underwent a reversible blue shift and narrowed upon exposure to CO in air at 500 degree centigrade. The observed chemical reactions are presumed to be associated with the reduction of the YSZ matrix and the oxidation of CO, through a charge-transfer reaction between YSZ-bound oxygen anions, formed through the dissociative adsorption of oxygen molecules on YSZ at high temperatures and the Au nanoparticles.

Efficient CO oxidation at low temperature on Au(III)
Article Abstract:
Different states of oxygen were prepared on an Au(III) surface by controlling the deposition temperature and oxygen coverage. Characterization of the electronic and geometric features of the oxygen states revealed that the various oxygen states were formed with respect to oxygen coverage deposited at 200 K, whereas larger islands with a well-ordered two-dimensional structure attributed to a surface oxide formed when oxygen is deposited at 400 K.
