“…O ¨zdemir et al prepared modified TiO 2 NPs using cotton fabric by hydrolysis of the TiCl 4 precursor solution over cotton fabric. 209 The modified TiO 2 NPs enhanced the photodegradation of rhodamine B, compared to the cotton fabric alone. The antibacterial activity of this modified TiO 2 NP was successfully tested against S. aureus (ATCC 6538) and E. coli (ATCC 25922) as representative strains of Gram-positive and Gram-negative bacteria, respectively.…”

The bentonite-Zn doped CoFe 2 O 4 photocatalysts were successfully synthesized for the first time by decorating magnetic Zn x Co 1À x Fe 2 O 4 nanoparticles onto the bentonite surface in order to enhance the photocatalytic performance of Zn doped CoFe 2 O 4 nanoparticles. We tried to thoroughly investigate how changes in Zn 2 + concentration affected the particle size, shape, magnetic properties, optical band gap, and photocatalytic activities of B-Zn x Co 1À x Fe 2 O 4 nanocomposites. The photodegradation of crystal violet (CV), a model reaction under visible light irradiations, was used to assess the photocatalytic activities of the samples. Compared to other samples, the B-Zn x Co 1À x Fe 2 O 4 (x = 0.5) showed the highest photocatalytic activity, which is best matched to the pseudo-first-order kinetic. According to investigations using reactive species capture, the superoxide radicals have the main role in the degrading process, while the hydroxyl radicals and holes have a secondary and minimal effect, respectively.

“…As morphologies have immense effects on the optical, electronic, and catalytic properties, the applications of TiO 2 are closely associated to its morphology and dimensions. One-dimensional spherical TiO 2 has been conventionally used for electronics, sensors, and antimicrobial applications [ 74 , 75 ]. Tubular TiO 2 has served as an emerging candidate for electrode materials used in electrochemical microdevices, which hold potential for energy delivery or harvesting in biological and medical fields [ 76 ].…”

Membrane technology has become increasingly popular and important for separation processes in industries, as well as for desalination and wastewater treatment. Over the last decade, the merger of nanotechnology and membrane technology in the development of nanocomposite membranes has emerged as a rapidly expanding research area. The key motivation driving the development of nanocomposite membranes is the pursuit of high-performance liquid separation membranes that can address the bottlenecks of conventionally used polymeric membranes. Nanostructured materials in the form of zero to three-dimensions exhibit unique dimension-dependent morphology and topology that have triggered considerable attention in various fields. While the surface hydrophilicity, antibacterial, and photocatalytic properties of TiO2 are particularly attractive for liquid separation membranes, the geometry-dependent properties of the nanocomposite membrane can be further fine-tuned by selecting the nanostructures with the right dimension. This review aims to provide an overview and comments on the state-of-the-art modifications of liquid separation membrane using TiO2 as a classical example of multidimensional nanomaterials. The performances of TiO2-incorporated nanocomposite membranes are discussed with attention placed on the special features rendered by their structures and dimensions. The innovations and breakthroughs made in the synthesis and modifications of structure-controlled TiO2 and its composites have enabled fascinating and advantageous properties for the development of high-performance nanocomposite membranes for liquid separation.
