Plasmonic Based Kinetic Analysis of Hydrogen Reactions within Au−YSZ Nanocomposites
Source abstract
Abstract
The kinetics of the hydrogen reaction on a nanocomposite film comprised of gold (Au) nanoparticles embedded within yttria-stabilized zirconia (YSZ) was determined through an analysis of the localized surface plasmon resonance (LSPR) of the Au nanoparticles. The LSPR peak of the Au nanoparticles was monitored as a function of time during exposure to 0.5−1.00% H 2 in a N 2 background at temperatures of 300, 400, and 500 °C. An analysis of the reaction kinetics shows a linear relation between the observed rate of reaction and P H 2 1/2, indicative of a H 2 dissociative adsorption mechanism. Signal transduction is thought to be due mainly to charge exchange from the chemisorption of atomic hydrogen. An Arrhenius analysis of the data determined the activation energy to be about 0.2 eV for the H 2 reaction.
