Study on Synthesis and Photocatalytic Activity of Porous Titania Nanotubes

open access: yesAdvances in Materials Science and Engineering, 2016
Using the common natural cellulose substance (filter paper) and triblock copolymer (Pluronic P123) micelles as dual templates, porous titania nanotubes with enhanced photocatalytic activity have been successfully synthesized through sol-gel methods ...

Ab Initio Study of Phase Stability in Doped TiO2

open access: yes, 2012
Ab-initio density functional theory (DFT) calculations of the relative stability of anatase and rutile polymorphs of TiO2 were carried using all-electron atomic orbitals methods with local density approximation (LDA).

Mechanical loss in state-of-the-art amorphous optical coatings

open access: yes, 2016
We present the results of mechanical characterizations of many different high-quality optical coatings made of ion-beam-sputtered titania-doped tantala and silica, developed originally for interferometric gravitational-wave detectors.

Spectroscopic and Morphological Studies of Metal-Organic and Metal-Free Dyes onto Titania Films for Dye-Sensitized Solar Cells

open access: yesInternational Journal of Photoenergy, 2013
We have investigated the spectroscopic behavior of three different sensitizers adsorbed onto titania thin films in order to gain information both on the electron transfer process from dye to titania and on the anchorage of the chromophore onto the ...

Porous alumina‐based ceramics with very low thermal conductivity prepared by the starch consolidation route

open access: yesInternational Journal of Ceramic Engineering & Science
Alumina‐based porous ceramics were fabricated via the starch consolidation casting route, using titanium oxide as a sintering additive. Alumina‐titania‐starch slurries with starch contents of 2.5, 5, 7.5, and 10 wt% relative to the alumina‐titania system

Propiedades mécanicas y tribólogicas de recubrimientos alumina/titania proyectados por oxifuel (spray llama)

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2008
In this paper the porosity, phases, mechanical properties and abrasive wear resistance of ceramic layers of Al2O3/TiO2 deposited using the flame spray process are evaluated. The proportion of titania has a strong influence on the porosity of the coating,

Activity of nanosized titania synthesized from thermal decomposition of titanium (IV) n-butoxide for the photocatalytic degradation of diuron

open access: yesScience and Technology of Advanced Materials, 2005
Nanoparticles of anatase titania were synthesized by the thermal decomposition of titanium (IV) n-butoxide in 1,4-butanediol. The powder obtained was characterized by various characterization techniques, such as XRD, BET, SEM and TEM, to confirm that it ...
