Titania-activated persulfate for environmental remediation: the-state-of-the-art

Catalysis reviews, 2021
In the last decade, a considerable body of literature has been devoted to advanced oxidation processes encompassed peroxy-sulfur species owing to their capacity to generate highly active radicals. These species fulfill two main objectives in AOPs: act as

Thin-Film Composite Membranes with a Hybrid Dimensional Titania Interlayer for Ultrapermeable Nanofiltration.

Nano letters (Print), 2022
The interfacial properties within a composite structure of membranes play a vital role in the separation properties and application performances. Building an interlayer can facilitate the formation of a highly selective layer as well as improve the ...

Wet-Chemistry Strong Metal-Support Interactions in Titania-Supported Au Catalysts.

Journal of the American Chemical Society, 2019
Classical strong metal-support interactions (SMSI), which play a crucial role in the preparation of supported metal nanoparticle catalysts, is one of the most important concepts in heterogeneous catalysis.

Nucleation of Titania Nanocrystals in Silica Titania Waveguides

Journal of Sol-Gel Science and Technology, 2003
SiO2(1-x)-TiO2(x) monomode waveguides at 632.8 nm, with x in the range 0.07-0.2 and thickness of about 0.4 mum, were deposited on silica substrates by a dip-coating technique. Nucleation of TiO2 nanocrystals and the growth of their size by thermal annealing up to 1300degreesC were studied by waveguided Raman scattering in the SiO2(08)-TiO2(0.2 ...

Titania–Silica Interfaces

The Journal of Physical Chemistry C, 2012
The photocatalytic activity of titanium dioxide is sometimes observed to increase upon addition of silica, but the origin of this enhancement is not clear. To shed light on this effect, we investigate the titania/silica system in case of perfect segregation using density functional theory.

Stagnation-point flow of an aqueous titania-copper hybrid nanofluid toward a wavy cylinder

International journal of numerical methods for heat & fluid flow, 2018
Purpose The purpose of this paper is to investigate analytically the steady general three-dimensional stagnation-point flow of an aqueous titania-copper hybrid nanofluid past a circular cylinder that has a sinusoidal radius variation.

Different Kinetic Degradation Of Methyl Orange By Nanostructured Titania: Titania Nanotube, Titania Nanofiber, And Titania Nanoparticle

Qatar Foundation Annual Research Forum Volume 2013 Issue 1, 2013
TiO2 is a semiconductor with photo-catalytic properties and is being thoroughly investigated for its use in the degradation of harmful environmental pollutants using photo-catalytic reactions. The effects of TiO2 nanoparticles and different structured TiO2 electrodes on methyl orange degradation using sunlight have been investigated.
