Enhancing photocatalytic ability of TiO2 films using gel-derived P/Si-TiO2 powder

Studying Some of Physical Properties of a Lead Doping Titanium Dioxide TiO₂: Pb with Different Ratios

“…The expansion of the z-axis and this expansion in the basal plane is due to an increase in crystal vacancies and vice versa for rutile in which the constant c has decreased. Its decrease in anatase at the first rate of doping while maintaining a constant value until the last percentage of doping due to the contraction of each of the x and y axes and a decrease in the possibility of voids resulting from the occurrence of fualt stacking during the process of natural crystal growth of the material according to this level of the crystal structure of the material and the occurrence of shrinkage of the quaternary crystal lattice, and the increase in the lattice constants is due to the increase in the distance between the crystal levels, and this agrees with the researcher Yu J, et al [5].…”

“…The lattice constants a (A°), b (A°) and c (A°) a for the tetragonal crystal system of the anatase, rutile and orthorhombic crystal system of the brookite phase were determined from the equations ( 4) and (5), respectively [18] & [33]:…”

“…After the sun's rays fall on this material, active oxygen is generated, which in turn purifies water from pollutants, bacteria, fungi, germs, organic materials, as well as toxic elements such as arsenic As and Chromium Cr [1][2][3]. Titanium was first discovered in 1971 by an English chemist and geologist William Gregor And years later, titanium dioxide TiO 2 was manufactured for use as a whitening ingredient used in toothpastes, a multifaceted compound used as a strong photocatalyst capable of breaking any organic compound if exposed to the sun [4][5][6][7][8][9][10][11][12][13][14][15], and therefore can be used in cleaning and bleaching fabrics and purifying water / waste water and air [16] and in many other industrial applications such as the iron, electronics and chemicals industry, all the way to the manufacture of cosmetics, batteries and solar cells [17] and hydrogen production because of its important physical and chemical properties. It has chemical stability and is chemically non-toxic [2,3] and a high static permittivity, and is characterized by an Eg energy gap ranging between 3.04-3.46 eV [18], as it has A high resistivity estimated at 10 12 Ω.cm at a temperature of 25C°.…”

Towards a Better Understanding of the Back-Side Illumination Mode on Photocatalytic Metal–Organic Chemical Vapour Deposition Coatings Used for Treating Wastewater Polluted by Pesticides

“…Xingwang et al [75] examined TiO 2 /Fe supported on AC, and Murgolo et al [66] coated stainless-steel meshes with TiO 2 ; both the coatings demonstrated stability and could be reused for 10 cycles of 60 min each. For sol-gel TiO 2 coatings, Hsuan-Fu et al [76] reported that the photocatalyst remained stable and could be reused for four cycles of 720 min each. In contrast, He et al [38] reported the leaching-induced deactivation of a WOx/TiO 2 photocatalyst supported by impregnation.…”
