Recently, wastewater treatment by photocatalytic oxidation processes with metal oxide nanomaterials and nanocomposites such as zinc oxide, titanium dioxide, zirconium dioxide, etc. using ultraviolet (UV) and visible light or even solar energy has added massive research importance. This waste removal technique using nanostructured photocatalysts is well known because of its effectiveness in disintegrating and mineralizing the unsafe organic pollutants such as organic pesticides, organohalogens, PAHs (Polycyclic Aromatic Hydrocarbons), surfactants, microorganisms, and other coloring agents in addition to the prospect of utilizing the solar and UV spectrum. The photocatalysts degrade the pollutants using light energy, which creates energetic electron in the metal oxide and thus generates hydroxyl radical, an oxidative mediator that can oxidize completely the organic pollutant in the wastewater. Altering the morphologies of metal oxide photocatalysts in nanoscale can further improve their photodegradation efficiency. Nanoscale features of the photocatalysts promote enhance light absorption and improved photon harvest property by refining the process of charge carrier generation and recombination at the semiconductor surfaces and in that way boost hydroxyl radicals. The literature covering semiconductor nanomaterials and nanocomposite-assisted photocatalysis-and, among those, metal oxide nanofibers-suggest that this is an attractive route for environmental remediation due to their capability of reaching complete mineralization of organic contaminants under mild reaction conditions such as room temperature and ambient atmospheric pressure with greater degradation performance. The main aim of this review is to highlight the most recent published work in the field of metal oxide nanofibrous photocatalyst-mediated degradation of organic pollutants and unsafe microorganisms present in wastewater. Finally, the recycling and reuse of photocatalysts for viable wastewater purification has also been conferred here and the latest examples given.

Electrospun polymeric core-shell nanocomposites are exploited as templates to manipulate molecular self-assembly for preparing structural lipid nanoparticles, during which the confinement effect of fibers together with their core-shell structure, the aqueous environment and the secondary interactions, all contributed synergistically to facilitate molecular self-aggregation to produce lipid nanoparticles with a drug entrapment efficiency of 95.9% with a sustained drug release profile.Electrospun nanobers have been demonstrated to be good templates for indirectly producing functional nano-objects such as inorganic nanotubes, carbon nanobers and brous hydrogel materials with encapsulated microbes.1-6 These were realized through a strategy that takes the nanobers as templates in a whole way by virtue of their physical congurations, i.e. through post-treatment of the nanober mats (for example by physical absorbance and removing the lament-forming polymer matrix, cross linking reactions, calcinations or carbonization).Most recently, electrospun monolithic composite nanobers were demonstrated to be good templates to directly manipulate the molecular self-assembly of multiple components for fabricating functional nano-objects in situ such as solid lipid nanoparticles and liposomes. 7,8 In contrast to the aforementioned studies, these were achieved by the virtue of the nanometer connement effect of the nanobers and the formulation of a polymeric composite in which the functional building blocks can disperse throughout the polymer matrix on a molecular scale. Similarly, composite microparticles produced by electrospraying were also effective templates for producing selfassembled nanoparticles by virtue of their connement effect on a microscale. 9Although all the nanober and composite microparticles have been demonstrated to be good templates in different ways and for different applications, they are products derived from single uid electrohydrodynamic atomisation (EHDA -electrospraying, electrospinning and e-jet printing 10 ) processes, which lack secondary microstructure characteristics. Nano-particle self-assembly was achieved mainly through the properties of the components in the nanobers (oen their solubility in special solvents). One of the powerful capabilities of EHDA processes is that they can copy structures from the macro world to products at the micro/nano scale.11 For example, through the interactions between the electrons and uid liquid, electrospinning and electrospraying can easily duplicate the structure of macro jet devices (such as concentric, side-by-side and triaxial spinnerets) to generate products with special microstructures such as core-shell nanobers/particles and side-by-side and tri-axial nanobers. 11-14Fibers and particles with secondary structure characteristics should be better templates for broader applications in manipulating molecular self-assembly, as well as designing and developing new advanced materials, than those generated by single uid processes. Combining two or ...
