Abstract
MCM-41 samples with increased hydrothermal stability could be successfully synthesized by adding additional salts like tetraalkylammonium bromide or sodium bromide to the synthesis gel. The increased stability is related to the increased condensation of the silanol groups during the formation of the mesostructure. Hydrothermally stable MCM-41 structures with different pore diameter can also be synthesized by this method using surfactants with varied chain length. © 2000 Elsevier Science B.V.
