Supported and self-bonded molecular sieve structures

open access: yesComptes Rendus. Chimie, 2005
Aspects of the preparation and features of organized molecular sieve structures are discussed. The account is mainly focused on authors’ contribution to the filed though a short list of recent achievements in the area is also given. The zeolite supported structures considered are zeolite films and coatings grown on various substrates either by a direct
