Structural and electronic properties of ion-exchangeable layered perovskites

2013

The modification of metal oxide surfaces with organic moieties has been widely studied as a method of preparing organic-inorganic hybrid materials for various applications. Among inorganic oxides, the ion-exchangeable layered perovskites, materials composed by perovskite-like slabs (ABO3, in which B is a small transition metal cation and A is a larger s-, d- or f-block cation) and intercalated cations, stimulated authors’ interest in reason of some encouraging electronic and reactive properties. In particular it is well known that the interlayer surface of layered-perovskites in their protonated form can be easily functionalized with organic groups, such as alcohols, organophosphonic acids,…
