Abstract
Isotherms of tetrachloromethane vapor adsorption/desorption on porous η-Al2O3 samples, which are prepared by the thermal decomposition of bayerite precipitated in the presence of several hydroxybenzenes, are measured. Using Nechaev's hypothesis that only hydroxybenzene molecules with strictly specified ionization potential are adsorbed from aqueous solutions on the oxide surface, it is demonstrated that the templated precipitation of η-Al2O3 leads to changes in the shapes of adsorption isotherms and hysteresis loops resulted from the fundamental changes in the pore shape of the forming adsorbents.
