“…According to Ghorani and Tucker, by controlling the process conditions and using different polymers, it is possible to obtain a variety of fiber cross‐sectional shapes and sizes, allowing their use in several materials, such as conductive or semiconductive polymers. In addition, it is possible to incorporate many properties, before or after electrospinning, to turn the resulting material into a promising tool as an adsorbent with numerous applications . Polymeric nanofiber membranes obtained through electrospinning have greater specific surface area and smaller pore sizes, and can be applied as adsorbent materials.…”

Nowadays, efficient, economical, and environmentally friendly materials for the removal of emerging contaminants from the aquatic environment have been sought. Electrospun nanofibrous membranes contain fibers with diameters of submicron or nanometer scale, making them very promising adsorbent materials for use in several areas. In this context, the present study aims to synthesize and apply polymeric nanofiber membranes for solid‐phase extraction of estriol from aqueous solution. Nanofiber membranes of poly(ε‐caprolactone) (PCL) and polyamide‐6 (PA‐6) were tested as adsorbent materials and characterized by different techniques. The electrospinning time was evaluated, and the highest removal obtained for the PA‐6 nanofiber was 76.5%, spun for 100 min, whereas for the PCL nanofiber, 80% time‐independent removal was obtained. The thinner nanofibers had a larger contact area, therefore higher removals, except for the PCL nanofiber, which presented exposed beads on smaller thicknesses that impaired their efficiency. Furthermore, the nanofiber membranes have been applied for the determination of 1.0 mg L−1 of E3 in superficial water sample with satisfactory results. These aspects demonstrate that the synthesized nanofibers present an efficient material for the extraction of estriol: of high simplicity, low cost, and using green chemistry. © 2018 Wiley Periodicals, Inc.

The photocatalytic activity of BPNs before and aer the surface modi-cation was investigated by photodegradation studies deploying cationic and anionic organic dyes.…”

“…To overcome the difficulty of removal of photocatalytic agents post-water treatment, photocatalytic membrane reactors have been developed using various membrane techniques ( Molinari et al 2000 , 2001 , 2002a , b ; Sopajaree et al 1999a , b ), but these processes are of high cost. On the other hand, electrospinning is a simple technique that yields nanofibers with excellent physicochemical properties(Gupta et al 2019 ; Moheman et al 2016 ; Sharma et al 2014 ), which are beneficial for the photocatalytic reaction due to higher mesoporosity and specific surface area. This enhances solar light absorption with visible light sensitivity, longer lifetimes of photogenerated charge carriers and long nanofibrous structure for efficient charge transfer and recovery.…”

Membrane technology is an advanced approach to making a healthier and cleaner environment. Using such catalytic membrane technology to get clean, usable water by removal of dye impurities as well as pathogenic microbes is the main goal behind the research work. Here, we present the synthesis and efficacy study of polymethyl methacrylate (PMMA)-based Ag/ ZnO/TiO 2 trimetallic bifunctional nanofibers with antibacterial and photocatalytic activity. The nanofibers have been proven to be effective for the degradation of methylene blue (MB 93.4%), rhodamine B (Rh 34.6%), auramine-O (Au 65.0%) and fuchsin basic (FB 69.8%) dyes individually within 90 min in daylight. The study is further extended in abating a mixture of these dyes from contaminated water using composite nanofibers. Also, in the case of a mixture of these dyes (3 ppm each), nanofibers show dye degradation efficiency (DDE) of 90.9% (MB), 62.4% (Au) and 90.3% (FB and Rh) in 60 min. The role of Ag nanoparticles with a synergic photocatalytic effect on ZnO and TiO 2 is also demonstrated. Also, PMMA/ZnO/TiO 2 composite fiber membrane in synergy with silver particles shows better antibacterial activity against Gram-negative bacteria E. coli, making PMMA/Ag/ZnO/TiO 2 fibers a promising candidate in water purification.
