Enhanced photocatalytic activity of microwave treated TiO2 pillared montmorillonite

Preparation and photocatalytic properties of visible light responsive N-doped TiO2/rectorite composites

“…Clay minerals often present a large specific surface area [19] for adsorption of organic pollutants, and embedding TiO 2 particles into clay matrices is expected to improve the photocatalytic properties of the catalyst [20]. Previous studies [21][22][23] indicated that TiO 2 /clay composites, as a porous structure material with a large specific surface area, had a very good photocatalytic property due to the high adsorption capability of clays and the photocatalytic ability of TiO 2 .…”

Removal of methylene blue from aqueous solution by electrophoretically deposited titania‐halloysite nanotubes coatings

“…Clay minerals are relatively cheap and have high specific surface area encouraging their usage as the adsorbent for pollutant removal . Titania‐clay nanocomposites have been used for the photocatalytic purification of air and water . Halloysite nanotubes (HNTs) are natural clay mineral with tubular nanostructure and the chemical formula of Al 2 Si 2 O 5 (OH) 4 .nH 2 O (n = 0 and 2 for dehydrated and hydrated states, respectively) .…”

“…[48][49][50] Titania-clay nanocomposites have been used for the photocatalytic purification of air and water. [51][52][53][54][55] Halloysite nanotubes (HNTs) are natural clay mineral with tubular nanostructure and the chemical formula of Al 2 Si 2 O 5 (OH) 4 .nH 2 O (n = 0 and 2 for dehydrated and hydrated states, respectively). [56][57][58] HNTs have been extensively used as the adsorbent [59][60][61][62][63] and catalytic support for titania.…”

Photooxidation of ethanol on Cu-layer silicate/TiO2 composite thin films

“…Supports with large specific surface areas such as layer silicates are capable of accelerating photooxidative processes and they form stable composites. According to Kun et al [23] the increased adsorption capacity is due to the large specific surface area of the clay mineral and to the incorporation of TiO 2 particles between the silicate layers [24,25]. This phenomenon, termed the synergistic effect of layer silicates is responsible for the high activity of TiO 2 nanoparticles in composites compared to pure TiO 2 .…”
