Description	Mezoporézní molekulová síta MCM-41 a MCM-48 byla syntetizována za mikrovlnných a hydrotermálních podmínek. Vlastnosti takto připravených materiálů byly zjištěny pomocí difrakce rentgenova záření, rastrovací elektronové mikroskopie, infračervené spektroskopie a adsorpce dusíku. Bylo pozorováno, že mezoporézní molekulová síta syntetizovaná za mikrovlnných podmínek vykazují vyšší aktivitu při oxidaci adamantanonu peroxidem vodíku na příslušný lakton (Baeyer-Villigerova oxidace). (cs) Synthesis of mesoporous molecular sieves MCM-41 and MCM-48 was carried out under microwave and hydrothermal conditions. Molecular sieves prepared were characterized using X-ray powder diffraction, scanning electron microscopy, nitrogen adsorption isotherms and infrared spectroscopy to evaluate the properties of these materials. It was observed that mesoporous molecular sieves synthesized under microwave conditions exhibit higher activity in oxidation of adamananone by hydrogen peroxide to the respective lactone (Baeyer-Villiger oxidation).
