TL;DR: Gold particle catalysts prepared from supports calcined at 500 degrees C have optimum catalytic activity in CO oxidation, and smallest gold particle size for supports, which show maximum monolayer type octahedral alumina on the titania surface.

TL;DR: In this article, polycrystalline tin oxide surfaces have been examined before and after reduction in 40 Torr of CO at 100 and 175 C using Auger electron spectroscopy (AES), electron Spectroscopy for Chemical Analysis (ESCA), ion scattering spectroscope (ISS), and electron stimulated desorption (ESD) and showed that the changes in surface composition and chemical states of the surface species generally are subtle for the reductive conditions used.
Abstract: Polycrystalline tin oxide surfaces have been examined before and after reduction in 40 Torr of CO at 100 and 175 C using Auger electron spectroscopy (AES), electron spectroscopy for chemical analysis (ESCA), ion scattering spectroscopy (ISS) and electron stimulated desorption (ESD) The changes in the surface composition and chemical states of the surface species generally are subtle for the reductive conditions used However, significant changes do occur with regard to the amounts and the chemical forms of the hydrogen-containing species remaining after both the 100 and 175 C reductions
