• -known examples [7]. Besides classical layered silicates, clays showing other morphologies, such as fibrous (sepiolite and palygorskite) and tubular (halloysite and imogolite) clays, could also be interesting nanoparticulated solids in this context [8][9][10][11]. Sepiolite (SEP) and palygorskite are

• irradiation (Table 1). Among the 2D clay-based solids (layered silicates), montmorillonite and other smectites used for assembly with diverse NPs exhibit excellent adsorption, rheological, ion-exchange, and swelling properties as well as a large relative surface area for incorporating the NPs. Kaolinite clay

• ), layered silicates such as smectites are of particular interest as they have been largely used in adsorption and catalysis applications due to their valuable properties as expandable interlayer space, low cost and environmentally friendly nature [71]. Similarly, fibrous silicates, i.e., palygorskite and

• multilayer films using layer-by-layer self-assembly has been reported by Ma and co-workers [103]. TiO2 NPs have been also precipitated in the presence of layered silicates such as montmorillonite and hectorite using Ti alkoxides or TiCl4 and TiCl3 as precursors. Similarly, ZnO NPs have been assembled with

• microparticulated layered silicates of the smectite family, giving rise to materials exhibiting interesting properties [8][9]. The immobilization of those NP on clay surfaces represents an advantage for the easier recovering of the photocatalyst from the reaction medium compared to ZnO NP alone. In recent years

• methodology in which it was possible to reach the delamination of layered silicates previously exchanged with long-chain alkylammonium cations (organoclays) [13]. In this way, organo-smectites and organo-vermiculites have been used to prepare a new type of nanocomposites consisting of delaminated layered

• SiO2 NP from the two alkoxide precursors may result in the formation of mixed oxides showing poorer photoactivity than the clay heterostructure containing only TiO2 NP. In the present work, we have explored a different approach to prepare ZnO/SiO2-clay heterostructures derived from layered silicates

Among the inorganic nano-scaled materials, layered silicates have been widely used as hosts for functional π-conjugated molecules (dyes) [8][9][10], and polymers [11][12][13][14][15], owing to their adsorption properties, ion-exchange ability, high specific surface area, and a two-dimensional (2D
