Titania tubes with tunable wall thickness were produced by the sol-gel reaction of titanium(IV) n-butoxide in the presence of rod-shaped calcite particles that act as templates. A shell of amorphous titania was deposited around the calcite particles by sol-gel synthesis. The titania was crystallized to the anatase or rutile phase by sintering at different temperatures, and then acid etching was...

UNLABELLED BACKGROUND The work aims at improving photocatalytic activity of titania under Vis light irradiation using modification by Sn ions and an original, simple synthesis method. Tin-doped titania catalysts were prepared by thermal hydrolysis of aqueous solutions of titanium peroxo-complexes in the presence of SnCl4 or SnCl2 using an original, proprietary "one pot" synthesis not employi...

Nb-doped SrTiO3 ceramics doped with the surface modification of nanosized titania was prepared via liquid phase deposition approach and subsequent sintered in an Ar atmosphere. The surface modification of nanosized titania significantly improved the ratio of the electrical conductivity to thermal conductivity of SrTiO3 ceramic doped with Nb, and has little impact on the Seebeck coefficient, thu...

Methylene blue is a toxic dye that extensively used as colorant in textile industries. Industrial effluent containing methylene blue, when drained into water bodies without proper treatment, poses serious threat to aquatic and human lives. In order protect the biocycle, various methods have been established detect remove hazardous dyes from aqueous systems. Electrochemical are preferred, owing ...

Activities during ethylene/1-hexene copolymerization were found to increase using the mixed titania/silica-supported MAO with rac-Et[Ind]2ZrCl2 metallocene catalyst. Energy Dispersive X-ray spectorcopy (EDX) indicated that the titania was apparently located on the outer surface of silica and acted as a spacer to anchor MAO to the silica surface. IR spectra revealed the Si-O-Ti stretching at 980...

Titania nanotube arrays (NTA) generated from anodizing processes are tested as the substrate for surface-assisted laser desorption/ionization mass spectrometry (SALDI MS). The background generated from titania NTA is very low, making the approach suitable for the analysis of small molecules. The upper detectable mass is approximately 29 kDa. Homogeneous sample deposition leads to good shot-to-s...
