The peaks related to anatase correspond to the values of 20 equal to 25.4[degrees], 37.8[degrees], 38.4[degrees], 48.0[degrees], 54.1[degrees], 55.2[degrees], 62.5[degrees], 69.0[degrees], 70.2[degrees], 75.3[degrees] and 82.7[degrees], identified in the diffratogram, Figure 1, which correspond respectively to the planes (101), (004), (112), (200), (105), (211), (204), (116), (220), (215) and (224).
It could be seen that the crystalline size of anatase TiO2 was decreased accordingly, which indicated that the addition of ATP was good for the dispersion of TiO2 particles and active species Ce, inhibited the growth of grain size of anatase TiO2.

3a), the undoped Ti[O.sub.2] film shows a sharp peak and the 5-Zr--Ti[O.sub.2] film, a weak peak at 2[theta] = 25.40[degrees] belonging to the anatase (101) phase (PDF powder diffraction-01-075-1573).
Amorph, brookite, anatase, and rutile forms of Ti[O.sub.2] nanoparticles (Grafen Chemical Industries, Ankara, Turkey) were coated with PEG and BSA.
[13] synthesized pure anatase, pure rutile, and mixed anatase-rutile cake-like particles and observed that anatase-rutile particles reached higher photocatalytic activity compared to powders of pure phases (anatase and rutile) and also higher than P25.
A crystallization mechanism of anodic films has been proposed by Chen and Zhou [13] by considering that amorphous, anatase, and rutile phases of Ti[O.sub.2] present a structure which is similar to reticular Ti[O.sub.6] octahedral units that can be coupled by sharing their edges (favouring the anatase structure) or their vertices (in the case of rutile).
The structural model of the anatase Ti[O.sub.2] (101) surface was constructed using periodic boundary, with the size of 10.88 x 11.32 x 24.35 [Angstrom] [3].
In this sense, considering the advantages that our 1D Ti[O.sub.2] nanostructures are more easily filterable than nanoparticles and can be easily removed from solutions--in addition to the fact that the efficiency of 1D Ti[O.sub.2] as bactericide under UV-A irradiation was only briefly explored--in this work, we assess the photocatalytic activity of 1D Ti[O.sub.2], obtained from nanoparticles with a controlled proportion of anatase and rutile made by the sol-gel method, for E.
Among numerous anode material candidates, Ti[O.sub.2] with anatase phase has been explored as a promising anode material for SIBs with low cost, abundance, environmental benignity, and excellent structural stability [11-13].
Samples (7) and (8) are mixtures of similar amounts of anatase and rutile, while sample (9) contains only rutile (see Table 1).
Based on grade, the titanium dioxide market has been classified into rutile and anatase. Rutile is the most stable form.
This compound have three crystalline phases: rutile (tetragonal structure), anatase (octahedral structure), brookite (orthorhombic structure), which according to the requirement of the electrostatic valence rule, each oxygen atom is shared by three octahedra.
