A series of catalysts with tungsten (W) loadings varying from 0.5 to 11.4 wt.% was prepared by WO 3 /ZrO 2 WO 3 incipient wetness impregnation. The surface coverage of these catalysts was monitored by ion scattering spectroscopy (ISS) and low-temperature CO adsorption. Comparable values for the sur
