“…In such cases, premature reactivity among the precursors impeded successful and continuous fabrications of well-defined hybrid nanofibers via unspinnable precipitates, clogged spinnerets, and densely beaded fibers. It was also evident from these studies that, along with the compositions, the resulted properties also depended strongly on the lateral position of the active entities [15].…”

“…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].…”

While simple mixing of the multiple nanostructural components might not necessarily satisfy the multiple functional requirements, this research work showed that such structural complexity demanded both strategic structural design and deliberate fabrication methods. As such, nanosilver-hybridized WO 3 nanofibers incorporating paramagnetic CoFe 2 O 4 nanoparticles were for the first time fabricated following three aspects of morphological control-bulk crystallinity, fiber chemical compositions, and surface modifications. Experimentally, co-precipitation, eletrospinning, and photodeposition were employed to synthesize CoFe 2 O 4 nanoparticles, generate magnetically recoverable solar light-active photocatalyst nanofibers, and decorate them with nanosilver, respectively. The successful synthetic steps represented a facile and scalable route to multifunctional nanocatalyst against waterborne pollutants with organic and microbial constituents via WO 3 photocatalytic system. The work extended to nanofiber fabrication using the NS LAB 500 Nanospider machine which allowed for the pilot-scale hybrid nanofibrous catalyst effective under natural sunlight towards elimination of a model waterborne pollutant.

Abstract-Photo-catalysis process needs electron transfer to make reaction happen. In this study we want to propose a material that can make the HeLa cells lysis which is titanium dioxide (TiO 2 ). This paper focus on the growth of rutile phased TiO 2 nanoflowers on FTO substrate for HeLa cells treatment. The surface morphology will be characterized under FESEM and XRD while UV-vis for its optical property. The TiO 2 is fabricated by using hydrothermal method. FESEM analysis shows the size of TiO 2 nanoflowers are in range between 30 nm to 400 nm. The surface topography can be able to give data about its grain size and roughness. The TiO 2 nanoflowers sample are confirm in rutile phase mostly at lattice plane (110). By do studying on the TiO 2 characteristic, we can say that as it is important factor to do HeLa cell treatment.

“…Decorating, not be confused with doping, involves the addition of a metal, such as silver (40), gold (41), copper (42), and platinum (43) to the external surface of the titania. Using silver as an example, Srisitthiratkul et al (40) decorated particles by dispersing titania particles in solution (1g L -1 ) with sonication for 10 minutes and subsequently adding 0.1 g L -1 silver nitrate with stirring for another 10 minutes. The benefit of decorating with silver comes from silver's antimicrobial activity.…”
