dc.description.abstractAbsolute surface coverages ( ) of a series of tungsten^alumina catalysts prepared by the equilibrium adsorption method were determined by ion scattering spectroscopy (ISS) and low-temperature CO adsorption. The CO values for theWcatalysts were very similar to those obtained with the ISS method, for a given W loading. A linear increase in Wcoverage with increasingW loading, reaching 55%coverage for the 13.1%Wsolid,was observed. The calculatedWcross-sections (22.0^24.5Ð2/W)were in agreement with other reports in the literature. Due to the inherent limitations of each method, the combined use of ISS and low-temperature COadsorption is recommended for estimating absolute surface coverages in tungsten^alumina catalysts.es_VE
