Influence of the synthesis parameter on the interlayer and framework structure of lamellar octadecyltrimethylammonium kanemite

Inorganic-organic nanostructures, used as host materials for selective adsorption of functional molecules and as mesostructured material precursors, can be constructed by the interlayer modification of inorganic layered materials with surfactants. The formation mechanism is mainly determined by the...
