In this article, the adsorption of NO x (x = 1, 2) gas molecules on the (001) surface of CoFeMnSi quaternary Heusler alloys has been investigated theoretically with density functional theory (DFT) calculations. The adsorption strength was estimated with adsorption energy (E a), magnitude of charge transfer (ΔQ), charge density difference (CDD), minimum distance between molecule and surface (d), and adsorption mechanism was analyzed with density of states. The results showed that unlike half-metallic nature of the bulk phase, the pristine CoFeMnSi(001) surface exhibited metallic character caused by the emergence of electronic states of the atoms in the top-most layer of the surface. It was found that both NO and NO2 molecules undergo chemical adsorption and strongly interact with the surface evidenced by the large value of E a and ΔQ. In particular, the NO x molecule dissociates into N and O atoms for some adsorption configurations. Bader charge analysis reveals that NO x molecules act as charge acceptors by drawing charge from the surface atoms through p–d hybridization. Such findings might be useful in the development of Heusler alloys based gas sensors.

“…In photocatalytic applications, the efficiency of doped TiO 2 materials depends on their shape and surface area. The use of porous nanostructured materials such as nanofibers, nanotubes, nanoparticles, and nanosheets with different properties provides advantages in many different application areas such as gas sensors, supercapacitors, and water treatment applications. ,, Nanostructured materials, especially TiO 2 in the nanoparticle form or thin films, were used to achieve the best water treatment performance . Although TiO 2 nanoparticles have a large surface area, their fixation and recovery are hardly difficult, and it causes secondary pollution in water.…”

In this study, TiO 2 -based ceramic nanofiber membranes in the system of TiO 2 −SiO 2 −Al 2 O 3 −ZrO 2 −CaO− CeO 2 were synthesized by combining sol−gel and electrospinning processes. In order to investigate the thermal treatment temperature effect, the obtained nanofiber membranes were calcined at different temperatures ranging from 550 to 850 °C. Different characterization methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and high-resolution transmission electron microscopy (HR-TEM) were conducted on the obtained membranes to investigate the structural and morphological properties of the nanofibers. The Brunauer−Emmett−Teller surface area of the nanofiber membranes was very high (46.6−149.2 m 2 /g) and decreased with increasing calcination temperature as expected. Photocatalytic activity investigations were determined using methylene blue (MB) as a model dye under UV and sunlight irradiation. High degradation performances were achieved with the calcination temperatures of 650 and 750 °C because of the high specific surface area and the anatase structure of the nanofiber membranes. Moreover, the ceramic membranes showed antibacterial activity against Escherichia coli as a Gram-negative bacterium and Staphylococcus aureus as a Gram-positive bacterium. The superior properties of the novel TiO 2 -based multi-oxide nanofiber membranes proved as a promising candidate for various industries, especially the removal of textile dyes from wastewater.
