Appl Clay Sci   42(3-4) 363-367   Jan 2009   [Refereed]
The TiO2 pillared fluoromica powder was kneaded with polylactic acid resin. The composite showed high photocatalytic activity for degradation of acetaldehyde and toluene gas, especially at the range of 1–3 wt.% pillared mica powder, and this photo...

Three kinds of TiO2-pillared clay were prepared from different raw clays (montmorillonite, saponite and fluorine mica). Their surface hydrophobicities and performances in adsorption-photocatalytic degradation of toluene, trichloroethylene, ethylen...

TiO2 nanoparticle in the pillared montmorillonite was crystallized to become anatase phase by treatment with aqueous hydrogen peroxide at room temperature without losing both the porous structure and the hydrophobicity of the pillared clay. The re...

Employing silica as a support of TiO2 reduced the inhibition effect of chloride anion on photocatalytic activity for degradation of dibutyl phthalate in water. This support effect was largely observed in the cases of silica having larger surface a...

Hydrophobicity of TiO2 pillared clay prepared from different raw clays increased with the order of the raw clay; saponite < montmorillonite < fluorine mica. This order agreed with that of performance in both adsorption and photocatalytic degradati...

TiO2 pillared clay was applied for the adsorption-photocatalytic degradation of the endocrine disruptors with various hydrophobicities (di-n-butyl phthalate, diethyl phthalate, dimethyl phthalate and bisphenol-A). The hydrothermal treatment develo...

Chem. Lett.   (8) 715-716   Aug 1999   [Refereed]
Titania-pillared clay could adsorb dibutyl phthalate(DBP), one of endocrine disruptors, and degrade it photocatalytically. Hydrothermal treatment of this material, which increased the crystallinity of titania pillars, enhanced the photocatalytic a...

A novel pillared clay, i.e. pillared montmorillonite with crystallized TiO2, has been developed as a highly active photocatalyst. The TiO2 pillars in pillared montmorillonite were crystallized to anatase by hydrothermal treatment, while the porosi...

Some molecules such as Pyridinum Chorolide (PC), Methylene Blue (MB) and VIctoria Pure Blue (VPB) were adsorbed on Alumina-pillared montmorillonite intercalated with different amount of pillar. The pillared montmorillonite was dispersed in adsorba...

Alumina-pillared montmorillonites with different amount of pillar were prepared. The interlayer distance of these specimens was independent on the amount of pillar, i.e., ca. 9Å. The distance between pillars was estimated to be 9 to 17Å. The pilla...
