“…The most intense XRD peak corresponding to the (101) face in the anatase crystal becomes stronger and sharper with an increase in annealing temperature from 400 to 600 °C due to the enhancement of crystallinity. The TiO 2 crystallite sizes were calculated from the (101) reflection of anatase using the Debye–Scherrer formula:

true boldd = K λ / β c o s θ

The current work aimed to study the effect of thermal treatment on the structural, optical, and photocatalytic properties of TiO2 nanoparticles synthesized by a novel large‐scale electrochemical method using pulse alternating current (PAC). The obtained titania was characterized via XRD, TEM, XPS, UV‐Vis DRS, PL, Raman and FTIR spectroscopy. The as‐prepared TiO2 was found to be poorly crystallized and partly amorphous. Following thermal annealing, the anatase structure is developed at temperatures of 400–600 °C. The photoreactivity of the TiO2 nanoparticles was evaluated for the degradation of methylene blue (MB) and rhodamin B (RhB) dyes under UVA irradiation. As shown, the adsorption properties and photocatalytic activity of the as‐prepared TiO2 strongly depend on the chemical nature of the dye. The enhanced photocatalytic performance for the MB and RhB degradation was observed for the sample annealed at 400 °C, which coincides with a balance between the degree of crystallinity, specific surface area, optical properties and efficiency of electron‐hole pair separation.

“…There are different methods for the TiO2 nanopowders preparation like thermal (ethanol thermal, hydrothermal and solvothermal) [6][7][8][9][10][11][12], dip coating [13], spin coating [14], electrochemical [15][16][17], chemical solvent [18], RF sputtering [19] and sol-gel [20][21][22][23][24][25]. The sol-gel process is one of the most successful techniques for preparing nanocrystalline TiO2 due to its flexibility in fabrication, low cost, and low processing temperature.…”

The synthesis of TiO2 co-doped by (Ce, Yb) rare earth couple has been realized. This couple of rare earth can convert a high-energy photon to two low energy photons to enhance the energy efficiency of silicon solar cells. The undoped, 2% Ce doped- and (2% Ce, 4% Yb) Codoped- Titanium oxide were prepared by the co-precipitation method. The Infrared spectroscopy FTIR-ATR analysis indicates a continuous visible absorption in the 750–400 cm–1 region, confirming the formation of a titanium-oxygen bond. The X-Ray Diffraction characterization showed the dominance of the rutile crystalline phase with the presence of anatase one and the calculated crystallite size is between 7 to 13 nm. The X-Ray Fluorescence confirms the insertion of the dopants while the Inductively Coupled Plasma Mass Spectrometry ICP-MS showed the ratio 2 between Ce and Yb concentration. The thermogravimetric analysis indicated that Ce/Yb doped titanium was thermally stable. The absorption in the UV-visible (200 and 1000 nm) has been improved proportionally with the dopants.

“…Many templates will lose their identity upon calcination but IL offers the advantage of easy recoverability and reuse. Liana et al 23 reported choline chloride-based IL-assisted titania synthesis using an electrochemical process. The reported study used choline chlorideethylene glycol and choline chloride-urea as synthesis medium and achieved anodically prepared titania with 8-18 nm crystallite size and 70 to 90 m 2 g À1 surface area.…”
