Oxygen chemisorption on supported gold corresponded to an Au/O ratio of 2:1 at 200/sup 0/C and 3-6 mm Hg oxygen initial pressure. The chemisorptions were conducted at 170/sup 0/-450/sup 0/C on catalysts that comprised 0.54-4.25Vertical Bar3< by wt of gold on alumina, silica, and magnesium oxide, that were pretreated in hydrogen or evacuated at up to 450/sup 0/C, and that were characterized by wide-angle X-ray scattering and transmission electron microscopy.
