Solution- and air-recoverable photocatalytic nanofibers by facile and cost-effective electrospinning and co-precipitation processes

Multifunctional metal and metal oxide hybrid nanomaterials for solar light photocatalyst and antibacterial applications

“…In our previous report [14], the magnetic nanoparticles were deposited onto the surface of titanium dioxide nanofibers following co-precipitation of Co(II) and Fe(II) salts in the presence of alkaline medium containing the nanofibers. Unfortunately, such alkaline condition was shown to be incompatible with tungsten oxide nanofibers as the nanofibers dissolved spontaneously.…”

“…Among promising material solutions, solar light-active photocatalytic materials with potent antibacterial property and recoverability would offer one of the most convenient and economical environmental mitigation platforms for both types of pollutions [13][14][15]. In particular, photocatalysts capable of utilizing naturally abundant solar energetic spectrum were of interest for elimination of airborne and water-soluble chemical pollution [16][17][18][19][20][21].…”

“…As a consequence, nanofibrous structures became design of interest to take advantage of the smaller degree of aggregation and higher active surface area, a factor highly beneficial in photocatalysis. For instance, TiO 2 -based nanofibers represented a class of one-directional materials exemplifying a platform for both readily dispersible materials and versatile foundations for further chemical modifications with metal or metal oxides [14,15,32,33].…”

“…Versatile platforms for physical and chemical variations, these functional nanofibrous materials carried wide ranges of components, including natural [39], organic [40], inorganic [41,42], and organicinorganic hybrid [43] modules. While conceptually effective in mitigation of waterborne chemical and biological contaminants, their practical uses implicated not only harsh conditions but also the need for materials' recoverability [8,14]. As the organic constituents often failed to meet these criteria, inorganics such as metals and their hybrids became potential front runners.…”

Recent progress in electrospinning TiO2 nanostructured photo‐anode of dye‐sensitized solar cells

“…prepared a composite photo‐anode of recyclable CoFe 2 O 4 NP and TiO 2 NF. They declared when the CoFe 2 O 4 content was 12 wt % the performance of the composite NF achieved best . This is because the cobalt and iron, as electron capture sites, reduced the electron hole recombination rate and improved the efficiency of electronic transport, which improved the performance of photo‐anode.…”
