“…However, this precursor produced bers that collapsed and fused easily, unlike in the case of either capillary needle or free-surface DC-electrospinning. [24][25][26][27][28][29][30][31][32][33]36,37 The fusion of AFES Ti(OBu) 4 /PVP bers can be attributed to the high density of brous ow and increased amount of residual solvent in collected bers. It has been determined that the PVP/HPC polymer blend with 1 : 1 mass ratio resulted in both good precursor spinnability and improved quality of collected brous material.…”

“…TiO 2 nanobers are mainly prepared by thermal processing of precursor bers fabricated by direct current (DC) electrospinning. [24][25][26][27][28][29][30] This simple method utilizes a static electric eld to generate the propagating liquid precursor jets that form bers upon drying. Usually, the precursor solution containing titanium alkoxide, polymer, and solvent in different molar ratios, is delivered through a capillary needle, which serves as the jet-generating electrode, and then solidied precursor bers are collected on an oppositely charged electrode.…”

“…After calcination, obtained TiO 2 nanofibers are transformed into crystallized forms (rutile and anatase) for efficient photocatalytic activity. TiO 2 nanofibers were also synthesized using titanium-tetraisopropoxide (TTIP) and tetrabutyl titanate (Ti(OBu) 4 ) as TiO 2 precursors [ 53 , 54 ]. The commercial-grade TiO 2 NPs Degussa (P25) has been used directly with a polymer blend for the fabrication of TiO 2 nanofibers which did not require a calcination step afterward [ 55 ].…”

The tremendous increase in the production and consumption of titanium dioxide (TiO2) nanoparticles (NPs) in numerous industrial products and applications has augmented the need to understand their role in wastewater treatment technologies. Likewise, the deleterious effects of wastewater on the environment and natural resources have compelled researchers to find out most suitable, economical and environment friendly approaches for its treatment. In this context, the use of TiO2 NPs as the representative of photocatalytic technology for industrial wastewater treatment is coming to the horizon. For centuries, the use of industrial wastewater to feed agriculture land has been a common practice across the globe and the sewage sludge generated from wastewater treatment plants is also used as fertilizer in agricultural soils. Therefore, it is necessary to be aware of possible exposure pathways of these NPs, especially in the perspective of wastewater treatment and their impacts on the agro-environment. This review highlights the potential exposure route of TiO2 NPs from industrial applications to wastewater treatment and its impacts on the agro-environment. Key elements of the review present the recent developments of TiO2 NPs in two main sectors including wastewater treatment and the agro-environment along with their potential exposure pathways. Furthermore, the direct exposure routes of these NPs from production to end-user consumption until their end phase needs to be studied in detail and optimization of their suitable applications and controlled use to ensure environmental safety.

“…First TiO 2 nanofibers were produced by using electrospinning technique according to our previous study [23]. Afterwards, these nanofibers were broken mechanically by ball milling method in order to obtain TiO 2 nanorods (diameter: 153±37 nm, length: 390±160 nm). )…”

Abstract. Composite electrodes consisting of TiO 2 nanoparticles (NPs)-TiO 2 nanorods (NRs) and poly (3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS) were prepared on a conductive glass substrate. The presence of TiO 2 in the composite structure was proved by X-ray diffraction (XRD) Raman and FTIR-ATR measurements. The surface morphologies of TiO 2 NP-PEDOT:PSS, TiO 2 NR-PEDOT:PSS and TiO 2 NP-TiO 2 NR-PEDOT:PSS electrodes were characterized by scanning electron microscopy (SEM). According to the cyclic voltammetry measurement (CV), the electrocatalytic activity of composite electrodes on the reduction of triiodide improved after TiO 2 addition compared with pristine PEDOT:PSS and platinum (Pt) electrodes. Electrochemical impedance spectroscopy (EIS) showed that the charge transfer resistance (R ct ) strongly depends on the morphologies (ratio between TiO 2 NP and TiO 2 NR) of the composite electrodes. It was found that R ct decreased by increasing the amount of TiO 2 nanorod in the whole mixture of TiO 2 nanoparticles and PEDOT:PSS.
