Colloidal zeolites and zeolite membranes
J. Mater. Chem., 2002 The synthesis of zeolite membranes and thin films using the secondary growth process is briefly described. In this process colloidal zeolite particles (sols) are prepared hydrothermally and then subsequently deposited on substrates to produce uniform layers of controlled thickness.

Silicon aluminium ordering in the framework of zeolites [PDF]
Bulletin of the Geological Society of Finland, 1985 The (Si, Al) ordering scheme in the framework of zeolites is reviewed, and four classes are recognized: 1 ‒ zeolites with Si:Al = 1 : 1 and a simple order given by the alternation of Si and Al; 2 ‒ zeolites with Si> Al and an ordered distribution; 3 ...

Cryogenic Hydrogen Adsorption onto H-, Li-, Na-Exchanged Zeolites with Various Si/Al Ratios
Adsorption Science & Technology, 2014 We investigated the hydrogen-adsorption properties of four zeolites (FAU-, MFI-, *BEA- and MOR-type zeolites) with various Si/Al ratios and charge cations (H + Li + or Na + ), focusing particularly on the measurements of isosteric heat of adsorption (Q ...
