Abstract
The catalytic properties of materials based on terbium-doped and nickel-modified mesoporous silica gels prepared by the high-temperature template method were studied. The surface morphology and textural characteristics of the obtained samples were studied by scanning electron microscopy, X-ray phase analysis, and inductively coupled plasma mass spectrometry. The catalytic activity of the obtained catalysts was studied in the hydrogenation reaction of benzene, m-, p-, and o-xylene in the temperature range of 80–170°C and at a hydrogen pressure of 3 atm. It was established that doping with terbium leads to an increase in the catalytic activity of the catalyst modified with nickel in the hydrogenation reaction of benzene derivatives. Therefore, it was shown that mesoporous silica gel doped with terbium and modified with nickel is an effective catalyst for the hydrogenation of benzene and xylenes.
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.
