Abstract
A series of Ag-containing catalysts for CO oxidation based on CeO2–Fe2O3@SBA-15 composites synthesized by salt encapsulation in the hybrid material Pluronic-P123@SBA-15 was obtained. The effect of a block copolymer of polyethylene glycol and polypropylene glycol Pluronic-P123 inside the SBA-15 structure (ordered mesoporous silicon dioxide) on the distribution and dispersion of the deposited CeO2 and Fe2O3 components is shown. The deposition of cerium and iron oxides on Pluronic@SBA-15 makes it possible to stabilize CeO2 and Fe2O3 in the form of highly dispersed particles evenly distributed on the surface of the carrier. It was shown that the use of CeO2 and Fe2O3 stabilized in the SBA-15 structure makes it possible to increase the activity of Ag-containing catalysts in the CO oxidation reaction compared with the Ag/SBA-15 catalyst.
期刊介绍：
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
