Hydrothermal stability and catalytic activity of aluminum-containing mesoporous ethane-silicas

Article Abstract:

Aluminum-incorporated mesoporous ethane-silica with hydrothermal ultrastability is synthesized by one-pot condensation of Al(OiPr)3 with 1,2-bis(trimethoxysilyl)ethane using octadecyltrimethylammonium chloride surfactant. The aluminum-containing mesoporous ethane-silicas are seen to be efficient catalysts for the alkylation of 2,4-di-tert-butylphenol by cinnamyl alcohol to yield a flavan.

Synthesis and properties of gamma-Fe2O3 nanoclusters within mesoporous aluminosilicate matrices

Article Abstract:

Evaporation-condensation of volatile Fe(CO)5 was used to produce Fe2O3 nanocrystals within a hexagonally packed mesoporous aluminosilicate matrix. The result indicates that iron oxide nanocrystals within the MCM-41 matrix showed high thermal stability and increased magnetization when calcinated at high temperatures.

Direct synthesis of Al-SBA-15 mesoporous materials via hydrolysis-controlled approach

Article Abstract:

The hydrolysis-controlled approach for the synthesis of aluminium-substituted mesoporous SBA-15 (Al-SBA-15) materials is presented. In this approach, the hydrolysis of the silicon precursor like tetraethyl orthosilicate is accelerated by fluoride.
