Selective oxidation of liquid hydrocarbons over photoirradiated TiO2 pillared clays

Synthesis and characterization of novel SiO2 and TiO2 co-pillared montmorillonite composite for adsorption and photocatalytic degradation of hydrophobic organic pollutants in water

“…The intercalation of TiO 2 and other inorganic cations into the interlayer of montmorillonite is one of the most promising methods to improve the adsorption performance and the photocatalytic activity of organic pollutants. As reported, TiO 2 pillared montmorillonite displayed larger specific surface area [5], higher selectivity [6] and better adsorption ability [7] to hydrophobic organic pollutants than that of pure TiO 2 . However, TiO 2 particles pillared in montmorillonite are often in amorphous phases, resulting in low photocatalytic activity.…”

Removal of aqueous toxic Hg(II) by synthesized TiO2 nanoparticles and TiO2/montmorillonite

“…Recently, TiO 2 composites have also been studied by preparing a series of compounds such as microcrystalline TiO 2 pillared clays, mixed Ti/Si, Ti/V oxides, nanocrystals of TiO 2 dispersed in inorganic media [28][29][30][31][32][33][34]. Some studies indicated that TiO 2 supported on porous adsorbents is a potential catalyst system for the continuous removal of contaminants from wastewaters [31,35].…”

Chapter Green Nanotechnology: Development of Nanomaterials for Environmental and Energy Applications

“…Selection by size has been researched by developing innovative photocatalytic materials with well-defined specific porous structures (147,(152)(153)(154). As an example, incorporation of TiO 2 particles into sheet silicates of clay was suggested (152).…”

“…As an example, incorporation of TiO 2 particles into sheet silicates of clay was suggested (152). Only molecules that are smaller than the distance between adjacent sheet layers are allowed to contact with the incorporated TiO 2 (153). Similarly, TiO 2 nanoparticles are grafted onto the surface of mesoporous silicates (154).…”
