摘要：

The silver surface area was determined quantitatively as a function of loading for Ag/α-Al2O3 catalysts. This relationship was found to be nonlinear and was attributed to the fact that strong interactions between the metal precursor and the support do not exist. Selective chemisorption of oxygen using the dynamic pulse technique was employed to measure the silver surface area. Additional characterization of the catalysts was carried out using SEM and XRD analyses. The results have direct relevance for optimal catalyst distribution studies. © 1993 by Academic Press, Inc.
