In situ ATR-FTIR study of H2O and D2O adsorption on TiO2 under UV irradiation.

In Situ ATR-FTIR Investigation of the Effects of H2O and D2O Adsorption on the TiO2 Surface

Photodegradation of Adsorbed Bovine Serum Albumin on TiO2 Anatase Investigated by In-Situ ATR-IR Spectroscopy.

A Fourier transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy study of the photodegradation of adsorbed bovine Serum Albumin (BSA) on porous TiO2 films was carried out. The experiments were performed in a flow-through cell in water at concentrations of 10-6 mol/L at room temperature. The curve fitting method of the second derivative spectra allowed us to explore details of th...

UV irradiation induced transformation of TiO2 nanoparticles in water: aggregation and photoreactivity.

Transformation of nanomaterials in aqueous environment has significant impact on their behavior in engineered application and natural system. In this paper, UV irradiation induced transformation of TiO2 nanoparticles in aqueous solutions was demonstrated, and its effect on the aggregation and photocatalytic reactivity of TiO2 was investigated. UV irradiation of a TiO2 nanoparticle suspension ac...

Effects of UV irradiation treated polycarbonate substrates on properties of nanocrystalline TiO2 sol-gel derived thin films

In this study, in order to achieve effective coating of the homogeneous titanium dioxide (TiO2) thin film, UV irradiation pre-treatment was carried out to activate PC surfaces before coating. Sol-gel-based nanocrystalline TiO2 thin films were prepared by employing tetrabutyl-titanate as a precursor. Nanocrystalline TiO2 thin films were deposited by sol-gel spin coating on the treated substrates...

Fabrication Fe3O4/SiO2/TiO2 Nanocomposites and Degradation of Rhodamine B Dyes under UV Light Irradiation

Recycling and reusing of catalyst is an important factor to produce capable and low cast catalysts. Silica coated magnetic nanoparticles (Fe3O4/SiO2) were synthesized via a simple sol-gel method with the aid of sonication. Fe3O4 nanoparticles. After that a layer of TiO2 was constricted by hydrolyze and condensation of Teteranormalbuthyltitanate to produce Fe3O4/SiO2/TiO2 nanocompsite. As-synthe...
