Structural Modifications on Germanosilicates

Popis výsledku v původním jazyce

(Chapter 5) This chapter examines the unique properties of germanosilicate zeolites which not only dictate their hydrolytic stability but also predetermine them for highly-controlled post-synthetic structural transformations and producing new types of porous materials. The germanosilicate zeolites commonly suffer from decreased hydrolytic stability compared to silicates and aluminosilicates. On one hand, the germanosilicates are susceptible to structural degradation in moist environment due to the weaker nature of the Ge-O bonds. On the other hand, the framework germanium shows pronounced preference for certain framework positions (e.g. double-4-rings) which enables to carry out the hydrolysis selectively. The selective hydrolysis of germanosilicate zeolites yields low-dimensional silicate materials, such as layered zeolite precursors. The chapter further demonstrates application of the zeolite layers as building blocks or starting compounds for preparation of materials with highly controlled chemical and structural properties via methods of intercalation, pillaring or the ADOR transformation.
