Study of the Adsorption Properties of Mesoporous Silica Modified with Silver and Doped with Cerium or Terbium Using Inverse Gas Chromatography
Abstract
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.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
