“…Figure 2A shows the morphology of the electrospun mat contained entwined zirconium n-propoxyl and titanium iso-propoxyl fibers; the obtained nanofibers are smooth, continuous, and bead-free, and ranging from 100 to 600 nm in diameter. Figure 2B shows that after the hydrothermal process, the produced nanofibers were not harshly affected, which is attributed to the polycondensation tendency of the used metal alkoxides precursors 38 . However, a few broken nanofibers may be observed, but the axial ratio is still large, which reflects the preservation of the main advantage of the nanofibrous morphology.…”

Capacitive deionization, as a second generation electrosorption technique to obtain water, is one of the most promising water desalination technologies. Yet; in order to achieve high CDI performance, a well-designed structure of the electrode materials is needed, and is in high demand. Here, a novel composite nitrogen-TiO2/ZrO2 nanofibers incorporated activated carbon (NACTZ) is synthesized for the first time with enhanced desalination efficiency as well as disinfection performance towards brackish water. Nitrogen and TiO2/ZrO2 nanofibers are used as the support of activated carbon to improve its low capacitance and hydrophobicity, which had dramatically limited its adequacy during the CDI process. Importantly, the as-fabricated NACTZ nanocomposite demonstrates enhanced electrochemical performance with significant specific capacitance of 691.78 F g−1, low internal resistance and good cycling stability. In addition, it offers a high capacitive deionization performance of NACTZ yield with electrosorptive capacity of 3.98 mg g−1, and, good antibacterial effects as well. This work will provide an effective solution for developing highly performance and low-cost design for CDI electrode materials.

“…Lots of efforts have been made to dope ZrO 2 with other nonmetals, metals, and semiconductors in order to improve light response. The effects of different compositions of TiO 2 / ZrO 2 nanofibers were reported in the photocatalytic degradation of MB dye; the nanofibers containing 40 wt% ZrO 2 displayed the best performance under visible light [56]. Table 2 lists the photocatalytic degradation of varied metal oxidebased composite nanofibers.…”

This chapter intends to review the state of the art of a new nanomaterial generation based on electrospun composite nanofibers for dye removal from wastewater. Natural polymer-based nanofibers, nanofibers with unique morphology, and carbon nanofibers were comprehensively reviewed as capable carriers for a broad spectrum of functional materials such as metal oxides, zeolite, graphene and graphene oxide (GO), and metal-organic frameworks (MOFs) in the application of dye removal. The various nanostructures, adsorption capacity, advantages, and drawbacks were discussed along with mechanistic actions in the adsorption process and photocatalytic performance that emphasize current research development, opportunities, and challenges. The chapter covers multiple intriguing topics with in-depth discussion and is a valuable reference for researchers who are working on nanomaterials and the treatment of colored waters.

“…The applications of TiO 2 and its modification to photocatalytic degradation of dyes (Zhang et al 2011a;Kordouli et al 2015), various organic pollutants (Man et al 2015;Yasin et al 2015) and reduction in heavy metals (Djellabi and Ghorab 2014;Ma et al 2015) have been reported by many researchers. To improve the photocatalytic degradation efficiency of TiO 2 , b-CD was added to the photocatalytic reaction.…”

A new wood-flour-based photocatalytic composite of wood flour/b-cyclodextrin/titanium dioxide (WF/b-CD/TiO 2 ) was synthesized via the photoinduced assembly method. For evaluation of the photocatalytic efficiency of methyl orange (MO) by WF/b-CD/TiO 2 , three materials of TiO 2 , b-CD/TiO 2 and WF/TiO 2 were prepared and assessed under the same photocatalytic conditions. The morphology of these composites was characterized by scanning electron microscope (SEM) and transmission electron microscope (TEM), respectively. The chemical composition was detected by X-ray photoelectron spectroscopy (XPS). By means of phenolphthalein probe technique and back titration method, the contents of active b-CD (3.5 %) and TiO 2 (0.0581 g/0.1 g) in the prepared WF/b-CD/TiO 2 composite were obtained. In the experiments of photocatalytic reaction, for completely degradation of 0.1 mmol L -1 MO, the degradation time of WF/b-CD/TiO 2 was similar to that of b-CD/TiO 2 but shorter than those degraded by pure TiO 2 and WF/TiO 2 . The kinetics of photocatalytic degradation of MO by WF/b-CD/TiO 2 was also investigated. The intraparticle diffusion kinetic model gave a better correlation for the photocatalytic reaction. In addition, after recycling for five times, the degradation efficiency of MO by WF/b-CD/TiO 2 was still above 86 %, which was obviously higher than that by WF/TiO 2 , indicating a good regeneration property.
