NOVEL REACTIVE AMINO-COMPOUND: TRIS(HYDROXYMETHYL)AMINOMETHANE COVALENTLY GRAFTED ON KAOLINITE

摘要

The covalently grafting of organic units on an inorganic matrix leads to materials combining functionalities of the organic ligands, such as light absorption, reactivity, and flexibility, with the specific properties of the support, such as chemical and thermal stability, giving rise to new materials with high functionalities and unique properties. Various inorganic matrices such as silica, zeolite, and titania have been employed in the development of hybrid organic-inorganic matrices. In this context, natural clays, and kaolinite in particular, have attracted attention due to their structural features, which consist of two types of interlayer surfaces, one formed by silicon tetrahedral sheets and another composed by aluminum octahedral sheets.
