Sentence examples for modification of titania from inspiring English sources

The results are analysed on a comparative basis to investigate the effect of in situ incorporation and in situ surface modification of titania on the composite properties.

Unlike modification of titania photoanode by coating with MgO which act as a barrier layer toward recombination, addition of MgO nanopowder to electrolyte prevents recombination through adsorption of anions (triiodide/iodide) from electrolyte.

Surface modification of titania by a silane coupling agent (bis- 3-triethoxysilylpropyl -tetrasulfide, TESPT) causes further improvement in filler dispersion and composite properties when added in the reactive sol-gel system during in situ titania generation rather than it's external addition in the titania filled Nbis- 3-triethoxysilylpropyl -tetrasulfide

The surface amines on the magnetic iron oxide NPs can serve as functional groups for further modification of titania.

Anatase is the preferred crystalline modification of titania as it provides a larger surface area compared with rutile [ 36– 38], which could lead to the hydrophobicity of small diameter nanotubes in their study.

The aim of this work was the synthesis of organic-inorganic composite by modification of titania-silica oxide with alginate and the comparison of the adsorption properties of initial silica-titania and it composite with alginate with respect to the heavy metal ions.

The main reason for the independence of the Seebeck coefficient on the surface modification of nanosized titania is that the carrier concentration not be affected by the surface modification of nanosized titania for it could not react with Nb-STO [10].

Seebeck coefficient was almost independent of nanosized titania addition, which was mainly due to the carrier concentration had not been affected by the surface modification of nanosized titania.

Fig. 1 SEM micrograph of raw Nb-STO powders with coated nano-sized titania Fig. 2 Temperature-dependent electric transport performances of Nb-STO composites with and without the surface modification of nanosized titania: a electrical conductivity, b Seebeck coefficient.

Fig. 5 SEM micrographs of Nb-STO composites with (a) and without the surface modification of nanosized titania (b).

It can be seen that the surface modification of nanosized titania obviously enhanced the grain growth of Nb-STO.
