[EN] IDM-1 is a new silica zeolite with an ordered and well-defined framework constructed by alternating pentasil layers and interrupted layers, giving rise to an intersecting system of straight medium pores and undulating ...
[EN] The synthesis of crystalline molecular sieves with pore dimensions that fill the gap between microporous and mesoporous materials is a matter of fundamental and industrial interest(1-3). The preparation of zeolitic ...
[EN] Porous materials such as zeolites contain well-defined pores in molecular dimensions and have important industrial
applications in catalysis, sorption and separation. Aluminosilicates with intersecting 10- and 12-ring ...
The combination of different experimental techniques, such as solid C-13 and H-1 magic-angle spinning NMR spectroscopy, fluorescence spectroscopy and powder X-ray diffraction, together with theoretical calculations allows ...
[EN] Zeolite Beta is accepted as a highly faulted intergrowth of two polymorphs, A and B, which are found in a 60:40 ratio. However, a polymorph C was also suggested as a hypothetical structure. Recently, pure silica ...
[EN] It was found that either polymorph B or polymorph C of zeolite beta can be obtained from the same structure directing agent: 4,4-dimethyl-4-azonia-tricyclo[5.2.2.0(2,6)] undec-8-ene hydroxide. The synthesis occurs ...
The synthesis of crystalline microporous materials containing large pores is in high demand by industry, especially for the use of these materials as catalysts in chemical processes involving bulky molecules. An extra-large-pore ...
