The critical evidence for/against FLPs in metal oxides is to establish wheter an adsorbed H2 molecule becomes dissociated across adjacent In and O sites on the surface. To probe this we will obtain vibrational spectra, which will be compared to calculated spectra, obtained from phonon calculations. Vibrational spectra will be measured for In2O3 nanorods with and without the presence of adsorbed H2. The In2O3 nanostructures will be grown in Toronto. We will then measure the vibrational spectrum at < 10K of the as-prepared samples. The samples will next be exposed to H2 gas and the the spectrum will once again be measured at < 10 K. Comparison of the measured spectra to those of possible atomistic models will allow us to indetify the species involved in the RWGS reaction.
