However, the MFI-ZSM5 membrane must be selected instead when moisture levels are ≤1vol%. In fact, at these conditions, the H2O/He separation factor for NaA barely exceeds 2, whereas it can be as high as 9.6 for MFI-ZSM5. Moreover, rather high permeances for H2O of around 1–2μ...
Moreover, the permeances of the binary mixture H2/D2, at the whole concentration range, were also measured at 298K to study the isotopic effects on the transport through the MFI-ZSM-5 membrane. We found that the mixed gas behaves macroscopically as a hydrogen isotopologue molecule, and its...
Zeolites are microporous materials consisting of a crystal structure with molecular sieving characteristics [1,2,3]. Zeolites have a wide range of applications when used as carriers to support metals for cross-coupling reactions, such as C-C coupling [4,5,6,7], C-N coupling [8,9,10], C...

employed a cationic polyelectrolyte as soft template to synthetize a porous carbon with a hierarchical nanostructure [27]. In general, the soft-template approach consists in the use of specific molecules to produce carbon materials with desired porosity. During a calcination process these molecules are...
