“…Additional cross-selection elemental mappings, combined with EDS analysis for SiO 2 @TiO 2 , showed the presence of Si, Ti and O as elements ( Figure 5) as expected. [25]. Additionally, it was observed that the diffractogram of the SiO 2 @TiO 2 coating was not affected by the use of sonochemistry on a macro scale.…”

“…Then, the scotch tape was removed from the opposite end of the application, forming a 180 • angle. Next, the coated area was compared with the patterns presented in Table 2 [22][23][24][25]. In addition, the adherence test was carried out before and after UV light exposure (0, 4 and 26 h), to determine the photocatalytic activity of the SiO 2 @TiO 2 coating.…”

“…To assess the durability of the SiO 2 , TiO 2 and SiO 2 @TiO 2 coated samples, an adherence test was performed following the ASTM 3359 [21] and the appropriate references [22][23][24][25][26][27]. In this case, the corresponding test for thin films with thicknesses less than or equal to 2 mm was selected.…”

Use of silicon dioxide (SiO 2 ) and titanium dioxide (TiO 2 ) have been widely investigated individually in coatings technology, but their combined properties promote compatibility for different innovative applications. For example, the photocatalytic properties of TiO 2 coatings, when exposed to UV light, have interesting environmental applications, such as air purification, self-cleaning and antibacterial properties. However, as reported in different pilot projects, serious durability problems, associated with the adhesion between the substrate and TiO 2 , have been evidenced. Thus, the aim of this work is to synthesize SiO 2 together with TiO 2 to increase the durability of the photocatalytic coating without affecting its photocatalytic potential. Therefore, synthesis using sonochemistry, synthesis without sonochemistry, physical characterization, photocatalytic evaluation, and durability of the SiO 2 , SiO 2 @TiO 2 and TiO 2 coatings are presented. Results indicate that using SiO 2 improved the durability of the TiO 2 coating without affecting its photocatalytic properties. Thus, this novel SiO 2 @TiO 2 coating shows potential for developing long-lasting, self-cleaning and air-purifying construction materials.

Starch‐based dual photo‐functional hydrogel (SDPH) was obtained via incorporating the azo group onto the backbone of polymeric network and titanium dioxide within the gel at the same time. The structure and composition of SDPH were confirmed with Fourier transform infrared spectrometer, ultraviolet‐visible (UV‐Vis) spectroscopy, thermogravimetric analysis, and energy scattering X‐ray spectroscopy. Scanning electron microscopy observation revealed that titanium dioxide was well dispersed within SDPH. It was found that SDPH not only showed a reversible light‐sensitive behavior but also possessed photo‐catalytic activity. Moreover, the dual photo‐characteristics could be modulated by simply varying the initial amount of titanium dioxide.

“…This fact motivated the research on this material in order to increase the surface area and/or shift its light absorption toward the visible spectral region. Many reports are devoted to novel synthesis methods resulting in a wide range of morphologies, such as mesoporous structures [4], microtubes [5], microdendrites, nanoparticles [6–8], nanorods [9–10], nanotubes [11–13], nanowires [14], and nanosheets [15–16]. Standing out from the rest of the synthesis techniques, electrochemical anodization produces vertically oriented, well-ordered nanotubular arrays with high aspect ratio.…”

Titanium oxide nanotubes (TNTs) were anodically grown in ethylene glycol electrolyte. The influence of the anodization time on their physicochemical and photoelectrochemical properties was evaluated. Concomitant with the anodization time, the NT length, fluorine content, and capacitance of the space charge region increased, affecting the opto-electronic properties (bandgap, bathochromic shift, band-edge position) and surface hydrophilicity of TiO2 NTs. These properties are at the origin of the photocatalytic activity (PCA), as proved with the photooxidation of methylene blue.
