“…Yet, the inline addition of TiO2 to the silica membranes did not significantly change the removal rate compared to non-functionalized samples. This can be explained by the shielding of TiO2 by the silica [36][37][38]. However, very interesting, the rate constants of dipcoated samples are significantly higher than those of inline functionalized samples for both PA 6 and silica.…”

Abbreviations 1 1 PA 6: polyamide 6, MB: Methylene Blue, IL: inline, DC: dip-coating, H: hydrophilic 2 ABSTRACT Titania has already proven its added value for air and water treatment. The higher the surface-to-volume area, the better the performance of the TiO2 photocatalyst. These nanoparticles are typically applied in a slurry form. The use of titania nanoparticles in suspension has, however, multiple disadvantages such as a high turbidity and complex recovery of the photocatalyst after use. Therefore, immobilization of titania nanoparticles on a porous support such as a nanofibrous membrane, can be highly valuable for water treatment. These TiO2 functionalized nanofibrous membranes may be used not only in a membrane separation reactor, but also in a contact reactor. In this study, TiO2 nanoparticles were immobilized on both polymer (polyamide 6) and ceramic (silica) nanofibrous membranes. Polymer nanofibers are chosen as they are the state-of-the-art material, silica nanofibers on the contrary are less studied but show additional advantages due their excellent chemical and thermal stability and can thus offer a clear benefit for a wider range of applications. Two immobilization techniques were used, namely inline functionalization and dip-coating. Inline functionalization showed to be the preferred method for polyamide 6 nanofibrous membranes, dip-coating for silica nanofibrous membranes. Complete degradation of isoproturon, an actual concern in water treatment, is shown. Even the widely available commercial TiO2 nanoparticles allowed for a complete isoproturon removal as the result of a correct immobilization process on nanofibrous materials. This clearly opens up the high value of TiO2 functionalized nanofibrous membranes for organic (micro)pollutants removal.

“…In the past decades, numerous studies have been carried out by researchers from all over the world on the application of heterogeneous photocatalytic oxidation process to decompose and mineralize certain recalcitrant contaminants. The photocatalytic activity of various forms of TiO 2 , such as TiO 2 film [8], TiO 2 powders [9], TiO 2 nanotubes [10], supported TiO 2 [11][12][13] and doped TiO 2 [14,15] have been evaluated through degradation of dyes and/or phenolic compounds under light irradiation. Results of these studies showed that TiO 2 was effective for removing dyes and phenolic compounds from aqueous solutions.…”

“…Since the silica surface is electrostatically stable, it also improves the dispersion of the core nanoparticles [17]. Although the overall particle stability and dispersibility can be improved after silica coating, the properties of the core component, such as reactivity and thermal stability, also may be modified [18,19]. This article presents our investigations regarding the influence of the silica coating on the photoreactivity, the cytotoxicity and the photo-killing ability of TiO 2 nanoparticles.…”

Highlights Core-shell structured TiO 2 -SiO 2 nanoparticles of varying shell thickness were synthesized as photo-killing agents.  The effect of the silica shell thickness on the photoreactivity, cytotoxicity, haemocompatibility and photo-killing ability of the TiO 2 nanoparticles was investigated.  Strong photo-killing effect and enhanced cytocompatibility were achieved by controlling the silica shell thickness to 5.5 nm. nanoparticles, but also demonstrated an improved cell compatibility and effective photokilling ability upon the mouse fibroblast cells (L929). *Highlights (for review)
