Catalytic properties of CeO2 and its nanocomposites with SBA-15 mesoporous molecular sieve in cyclic carbamates production from CO2 and aminoalcohols

Abstract

A serie of CeO₂ materials and its composites with SBA-15 were obtained by decomposition of cerium ammonium nitrate at different temperatures and tested as catlyst for cyclic carbonates production from CO₂ and aminoalcohols. It was shown that reducing the decomposition temperature of cerium dioxide precursor from 500 to 300℃ led to an increase in the conversion of 2-aminoethan-1-ol in the process of obtaining 1,3-oxazolidin-2-one under carbon dioxide pressure from 14 to 84%, which can be explained by an increase in defects with Ce³⁺ while for CeO₂/SBA-15 composites are inactive due to the adsorption of 2-aminoethan-1-ol on silanol groups of the surface and the absence Ce³⁺patricles in formed composites..
