Isotherms for the adsorpton/desorption of N2 at 77 K onto metallic silver/activated carbons after acid treatment are of Type I with a small amount of capillary condensation hysteresis. The PSD calculated for our materials using the density functional theory confirms our hypothesis regarding the source of the microporosity being the metallic silver on the activated carbon surfaces after acid treatment. In SEM images, we obserrve highly developed surface structures and homogeneously distributed metals on the carbon surface. The IR spectra of a metallic silver/activated carbons show that acid treatment is associated consequently with the homogeneous distribution of metal upon increasing the surface acidity of the activated carbons. The effects of surface acidity and basicity calculated using the Boehm titration method were also evaluated from correlations as a function of NaOH, NaHCO3 and Na2CO3 uptake. Finally, the results of typical EDX elemental microanalyses of Ag/activated carbons after acid treatment suggest that almost all of the samples became increasingly rich in silver upon increasing the amount of acid with which they were treated.
