Hybrid and biohybrid silicate based materials: molecular vs. block-assembling bottom–up processes

Confinement of a Nonionic Surfactant Membrane Within a Montmorillonite as a New Way to Prepare Organoclay Materials

“…Smectite clay minerals such as Wyoming montmorillonite display, in presence of water, cation exchange capacities (CEC), swelling, hydration properties and a high surface area which lead to strong adsorption properties. These properties have been highlighted in several applications involving catalysis, nanocomposite materials, geochemical barriers in the case of waste landfills as well as potential sorbents for water remediation [1][2][3][4][5][6][7][8] . The structure of dioctahedral smectite is represented by two Si 4 O 10 tetrahedral sheets of sandwiching an aluminum (Al 4 (OH) 12 ) or a magnesium (Mg 6 (OH) 12 ) octahedral sheet.…”

“…The adsorption process of guest molecules on smectite clay minerals mainly supports an ion exchange with the interlayer cations or counterions [1][2][3] . Many studies have been devoted to the synthesis of cationic organoclays [1][2][3] .…”

“…One process of synthesis is the use of layered porous materials such as Layered Double Hydroxides (LDHs) or smectite as host structures for the orientation of guest molecules [1][2][3] . Smectite clay minerals such as Wyoming montmorillonite display, in presence of water, cation exchange capacities (CEC), swelling, hydration properties and a high surface area which lead to strong adsorption properties.…”

“…Many studies have been devoted to the synthesis of cationic organoclays [1][2][3] . These materials are obtained after an ion exchange with quaternary ammonium cationic surfactant.…”

Crystal architectures of a layered silicate on monodisperse spherical silica particles cause the topochemical expansion of the core-shell particles

“…zeolites and mesoporous solids). [1][2][3][4] Inorganicorganic periodic materials such as metal-organic frameworks, porous coordination polymers [5,6] and crystal-like periodic organosilicas, [7,8] have been of increasing interest because the organic moieties are spatially arranged in regular patterns in these materials.…”
