Samples of mesoporous silica gel doped with cerium and terbium and modified with silver were synthesized using the template method. The textural and morphological characteristics of the samples were studied using scanning electron microscopy, inductively coupled plasma mass spectrometry, X-ray diffraction analysis, Fourier-transform infrared (FT-IR) spectroscopy, and nitrogen adsorption-desorption analysis. Moreover, thermodynamic characteristics of adsorption (differential heats and entropies) of test organic compounds were obtained using the inverse gas chromatography method. It was established that the nature of the dopant leads to changes in the textural characteristics of the samples and the heat of adsorption for hydrocarbons and compounds prone to various types of specific interactions.
