The influence of synthesis parameters (e.g. Si/Al ratio, pH of the reaction mixture, structure of Gemini-type surfactant) on the phase selectivity of nanocrystalline MOR formation was studied. The nature of organic structure-directing cation (i.e. ch

The morphology of hierarchical zeolite nanocrystals with MOR, BEA, MFI, and MTW topology has a significant effect on the accessibility of the Bronsted and Lewis acid centers, the concentration and strength of which are determined by the type and conc

The strength of the acid sites in isostructural hierarchical porous zeolites increases in the order BSiO < GaSiO < AlSiO, and the concentration in the structural types increases in the order MTW < BEA < MOR. Zeolite materials with BEA and MOR topolog

Structure transformation of germanosilicate zeolites ITH, ITR, and IWR containing hydrolytically unstable interlayer Ge–O bonds was investigated and is related to the conditions of acidic treatment (i.e., concentration of hydrochloric acid, tempera
