| Description
| - Serie vzorků siliky MCM-41 byla připravena pomocí směsí 1-alkyl-3-metylimidazoliové soli s alkyltrimethylamoniovou solí nebo pomocí směsí dvou různých 1-alkyl-3-metylimidazoliových solí, které působily jako činidla řídící strukturu. (Alkyl označuje oktyl či hexadecyl.) Precipitace tuhých částic z homogenního roztoku metasilikátu sodného a směsi surfaktantů nastávala v důsledku snížení pH, které bylo vyvoláno hydrolyzou etylesteru kyseliny octové. Připravená molekulová síta byla charakterizována rastrovací a transmisní elektronovu mikroskopií, difrakcí Rentgenova záření a adsorpcí dusíku. Texturní parametry byly vypočteny z adsorpčních dat za použití statistiko-termodynamických metod. Všechny připravené siliky byly typu MCM-41; navzájem se lišily integrální šířkou distribuce mesopórů a přítomností mesopórů sekundárních. (cs)
- A series of samples of MCM-41 silica was synthesized using surfactant blends of 1-alkyl-3-methylimidazolium and alkyltrimethylammonium salts or blends of two different 1-alkyl-3-methylimidazolium salts (alkyl denotes octyl or hexadecyl) as structure-directing agents. The precipitation of solid particles from a homogeneous water solution of sodium metasilicate and surfactant blend was achieved by lowering the pH due to the hydrolysis of ethyl acetate added. The molecular sieves were characterized by scanning as well as transmission electron microscopy, X-ray powder diffraction, and nitrogen adsorption using a proper nonlocal density functional theory approach for calculations of the textural parameters. All the prepared silicas were of MCM-41-type; they differ in the integral breadth of the pore size distribution curve and the presence of secondary mesopores.
