“…Significantly, the FeOx/PES hybrid showed remarkable degradation and mineralization of the target compounds in both wastewater matrices in the presence of PMS. This underpins the synergy between photocatalysis and PMS-mediated oxidation [97]. In addition to abatement of pollution by pharmaceutical drugs, magnetron-sputtered coatings have been explored for the degradation of textile dyes and phenolic compounds, which is an indication of the versatile application of these coatings.…”

The current economic and ecological situation encourages the use of steel to push the technological limits and offer more cost-effective products. The enhancement of steel properties like wear, corrosion, and oxidation resistance is achieved by the addition of small amounts of chemical elements such as Cr, Ni, Si, N, etc. The steel surface can be protected by different treatments such as heating and coating, among others. For many decades, coatings have been an effective solution to protect materials using thin hard films. Several technologies for thin film deposition have been developed. However, some of them are restricted to certain fields because of their complex operating conditions. In addition, some deposition techniques cannot be applied to a large substrate surface type. The magnetron sputtering deposition process is a good option to overcome these challenges and can be used with different substrates of varying sizes with specific growth modes and for a wide range of applications. In this review article, we present the sputtering mechanism and film growth modes and focus on the mechanical and tribological behavior of nitride thin films deposited by the magnetron sputtering technique as a function of process conditions, particularly bias voltage and nitrogen percentage. The biomedical properties of transition metal nitride coatings are also presented.

“…Adding to this it improves the photoreactors compactness due to the integration of light source in the photocatalytic support. The recyclability of the catalyst is an important factor from both environmental and economic points of view [40]. To examine this parameter, the luminous textile underwent two cycles of photocatalysis under the same operating conditions (Figure 8).…”

“…Textile materials have been efficiently used for immobilization of affinity ligands, polysaccharides, ionic liquids, enzymes , or (nano)particles. − For example, manganese dioxide microparticles adsorbed on nonwoven fabric fibers were used as a recoverable catalyst for hydrogen peroxide decomposition, while textile modified with silver nanoparticles exhibited antibacterial properties . Recently, different types of textile materials were modified by iron oxide (nano)particles or microfibers to obtain composites exhibiting interesting properties, such as electromagnetic shielding, , removal of important pollutants from water sources, degradation of selected organic dyes, possibility of immobilization of biologically active compounds and cells, or to prepare new types of colored textiles . In specific cases, simultaneous magnetic, photocatalytic, sonocatalytic, antibacterial, and antifungal activities have been found in iron-oxide-modified textile .…”

At present, both native and immobilized nanoparticles are of great importance in many areas of science and technology. In this paper, we have studied magnetic iron oxide nanoparticles and their aggregates bound on woven cotton textiles employing two simple modification procedures. One modification was based on the treatment of textiles with perchloric-acidstabilized magnetic fluid diluted with methanol followed by drying. The second procedure was based on the microwave-assisted conversion of ferrous sulfate at high pH followed by drying. The structure and functional properties of these modified textiles were analyzed in detail. Scanning electron microscopy of native and modified textiles clearly showed the presence of iron oxide nanoparticles on the surface of the modified cotton fibers. All of the modified textile materials exhibited light to dark brown color depending on the amount of the bound iron oxide particles. Magnetic measurements showed that the saturation magnetization values reflect the amount of magnetic nanoparticles present in the modified textiles. Small-angle X-ray and neutron scattering measurements were conducted for the detailed structural characterization at the nanoscale of both the native and magnetically modified textiles, and different structural organization of nanoparticles in the two kinds of textile samples were concluded. The textile-bound iron oxide particles exhibited peroxidase-like activity when the N,N-diethyl-p-phenylenediamine sulfate salt was used as a substrate; this nanozyme activity enabled rapid decolorization of crystal violet in the presence of hydrogen peroxide. The deposition of a sufficient amount of iron oxide particles on textiles enabled their simple magnetic separation from large volumes of solutions; if necessary, the magnetic response of the modified textiles can be simply increased by incorporation of a piece of magnetic iron wire. The simplicity of the immobilized nanozyme preparation and the low cost of all the precursors enable its widespread application, such as decolorization and degradation of selected organic dyes and other important pollutants. Other types of textilebound nanozymes can be prepared and used as low-cost catalysts for a variety of applications.
