Characterization of regular and plugged SBA-15 silicas by using adsorption and inverse carbon replication and explanation of the plug formation mechanism

Article Abstract:

A series of SBA-15 silicas are synthesized using triblock copolymer templates. This study explains the characterization of the SBA-15 silicas and indicates that the tetraethyl orthosilicate (TEOS) that hydrolyzes and condenses more slowly, solubilizes in the copolymer template in the SBA-15 pores, or displaces the template, and then condenses to form the plugs.

Functionalized MCM-41 and CEMCM-41 materials synthesized via interfacial reactions

Article Abstract:

Pure-silica and cerium-substituted mesoporous materials with tailored surface functionality are prepared by template displacement by organosilanes procedure. These two self-assembled mesostructured systems exhibit hexagonal arrangement of mesopores but they show different reactivity with respect to organosilanes.

Adsorption and thermogravimetric characterization of mesoporous materials with uniform organic-inorganic frameworks

Article Abstract:

Two-dimensional hexagonal HMM-1 and three-dimensional hexagonal HMM-2 ordered mesoporous materials with hybrid ethane silica frameworks are characterized using nitrogen adsorption, argon adsorption and high-resolution thermogravimetry under nitrogen and air atmosphere.
