Chemisorption of CO and CO2 on gold-supported ThO2 films
- 1. Lawrence Livermore National Lab., CA
Description
The chemisorption of CO and CO2 on gold-supported ThO2 films has been studied by X-ray photoelectron spectroscopy (XPS). At pressures of approx. 10-5 Pa both gases were found to adsorb without dissociating at room temperature. The ThO2 films were prepared by drying and calcining a Th(NO3)4-ThO2 slurry which was painted onto a gold substrate. Films prepared in this manner were mechanically and chemically stable, and were characterized by Auger electron spectroscopy (AES), X-ray photoelectron spectrosocpy (XPS), X-ray diffraction, and scanning electron microscopy (SEM). The calculated atomic sensitivity factor (ASF) for the Th(4f7/2) photoelectron peak (6.7) is in relatively good agreement with the value recently reported in the literature
