Полифункциональные химические материалы и технологии. [Т. 2] : материалы Международной научной конференции, 22-25 мая 2019 г Т. 2. С. 90-91Abstract: The interest in Ag-CeO2 catalysts for catalysis and photocatalysis is due to high catalytic activity, regeneration
feasibility, relatively low cost, and environmental safety. Mesoporous silica SBA-15 is considered as a prospective
support due to high surface area and pore volume. The series of Ag/SBA-15, CeO2/SBA-15, and Ag-CeO2/SBA-15 was
synthesized by wetness impregnation of SBA-15 that had been obtained by template synthesis using Pluronic P-123
triblock copolymer. Catalysts were investigated by low temperature nitrogen adsorption, UV-vis DRS, TPR-H2, and
SAXS. The research represented that combination of citric acid doping, application of SBA-15 pores as nanoreactors,
and stabilizing properties of triblock copolymer allows to synthesize highly active silver and ceria particles smaller than
5 nm, uniformly distributed in ordered mesoporous matrix of SBA-15
