Titania has properties that enable it to be used in a variety of applications, including self-cleaning surfaces, air and water purification systems, hydrogen evolution, and photoelectrochemical conversion. In order to improve the properties of titanium dioxide, modifications are made to obtain oxide/hybrid systems that are intended to have the properties of both components. In particular, zinc oxide, zirconia and molybdenum disulfide have been proposed as the second component of binary systems due to their antibacterial, electrochemical and photocatalytic properties. This paper presents a review of the current state of knowledge on the synthesis and practical utility of TiO2-ZnO and TiO2-ZrO2 oxide systems and TiO2-MoS2 hybrid materials. The first part focuses on the hydrothermal method; then a review is made of the literature on the synthesis of the aforementioned materials using the sol-gel method. In the last section, the literature on the electrospinning method of synthesis is reviewed. The most significant physico-chemical, structural and dispersive-morphological properties of binary hybrid systems based on TiO2 are described. A key aim of this review is to indicate the properties of TiO2-ZnO, TiO2-ZrO2 and TiO2-MoS2 hybrid systems that have the greatest importance for practical applications. The variety of utilities of titania-based hybrid materials is emphasized.

Nickel oxide-gadolinium doped ceria (NiO– Ce0.8Gd0.2O1.9) deserves special attention because of its high ionic conductivity. The nanocomposite fibers of this material are suitable as anode materials for low-temperature SOFCs. The composition and morphology of the nanofibers which prepared via electrospinning method were characterized by SEM, TEM and EDS. It was noticed that the fiber diameters gradually decreased from 190±77 nm to 75±27 nm by increasing the calcination temperature from 800 °C to 1000 °C. Further, the influence of the different parameters such as concentration of the polymeric pre-spinnable solution (CPS), concentration of the cationic solution (CCS), the applied voltage, tip-target distance, feed rate, diameter of the needle and the calcination temperature on the morphology of the fibers were investigated.

“…Coupled photocatalytic nanofibers can also be electrospun to enhance the overall photocatalytic performance. For example, a composite of ZnO-TiO 2 nanofibers prepared by an electrospinning technique whereby TiO 2 and ZnO precursors were mixed with PVP polymer solution for electrospinning showed higher photocatalytic degradation of methylene blue compared to TiO 2 and ZnO alone as reported by Wang et al [ 86 ]. In another study, ZnO-TiO 2 composite nanofibers prepared by Hwang et al were used for a bactericidal application.…”

This review paper systematically evaluates current progress on the development and performance of photocatalytic nanofiber membranes often used in the removal of micropollutants from water systems. It is demonstrated that nanofiber membranes serve as excellent support materials for photocatalytic nanoparticles, leading to nanofiber membranes with enhanced optical properties, as well as improved recovery, recyclability, and reusability. The tremendous performance of photocatalytic membranes is attributed to the photogenerated reactive oxygen species such as hydroxyl radicals, singlet oxygen, and superoxide anion radicals introduced by catalytic nanoparticles such as TiO2 and ZnO upon light irradiation. Hydroxyl radicals are the most reactive species responsible for most of the photodegradation processes of these unwanted pollutants. The review also demonstrates that self-cleaning and antimicrobial nanofiber membranes are useful in the removal of microbial species in water. These unique materials are also applicable in other fields such as wound dressing since the membrane allows for oxygen flow in wounds to heal while antimicrobial agents protect wounds against infections. It is demonstrated that antimicrobial activities against bacteria and photocatalytic degradation of micropollutants significantly reduce membrane fouling. Therefore, the review demonstrates that electrospun photocatalytic nanofiber membranes with antimicrobial activity form efficient cost-effective multifunctional composite materials for the removal of unwanted species in water and for use in various other applications such as filtration, adsorption and electrocatalysis.
