Immobilization of Cationic Titanium Dioxide (TiO2+) on Electrospun Nanofibrous Mat: Synthesis, Characterization, and Potential Environmental Application

Evaluation of the Photocatalytic Activity and Anticorrosion Performance of Electrospun Fibers Doped with Metallic Oxides

“…According to this, it can be concluded that a higher amount of these precursors was grafted in the fiber surface and contributed to a larger fiber diameter [56]. In addition, SEM images were also made in order to corroborate the presence of the resultant metallic oxide precursors in the electrospun fibers (see Figure 8).…”

“…It can be clearly appreciated that thermal treatment of the PAA + β-CD fibers induced the formation of highly crosslinked fibers with a change in the resultant aspect from slightly transparent to white-colored, showing better water stability, because the thermally treated electrospun fibers were not removed from the substrate after long-term water immersion. A similar approach, based on the application of a specific thermal treatment for obtaining highly crosslinked fibrous mats, is presented in [56] by using poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) as electrospun polymeric precursors.…”

Once this enhancement in the resultant water stability was confirmed, it was also demonstrated that this heat treatment also induced an increase in the adhesion of the fiber mats onto the underlying substrate [57][58][59], which is a key point for further implementation in industrial applications.…”

Morphological study of stabilization and carbonization of polyacrylonitrile/TiO2 nanofiber mats

“…Alternatively, tetran-butyl titanate (Ti(C 4 H 9 O) 4 ) can be used, 23,25,26 a material which is also flammable and in addition, corrosive and toxic. Only few reports can be found in the literature about coating electrospun nanofibers with TiO 2 nanoparticles; [28][29][30][31] however, immobilization of the TiO 2 particles on the nanofiber surface is not easy.…”

Modification of fibrous membrane for organic and pathogenic contaminants removal: from design to application

“…1,5,6 Among various water remediation technologies, advanced oxidation processes (AOPs), which are based on the generation of reactive oxygen species (ROS), are regarded as an effective technology for the degradation of hazardous organic pollutants in wastewater. [7][8][9][10][11][12][13] Fenton and Fenton-like treatments are best due to their high degradation ability, range of applicability and cost-effectiveness. [14][15][16][17] However, homogeneous Fenton-like degradation processes containing free reagents (iron ions and hydrogen peroxide) have some critical disadvantages, which is unacceptable for commercial applications such as selective reaction conditions (acidic pH), generation of iron sludge and single-use reagent is a costly and counterproductive procedure.…”
