“…The impact of catalyst loading has been frequently reported in the literature with the optimum concentration typically being 0.5-1 g/L [1,15,27,28]. This was also confirmed by the data that is shown in Figure 3, which identifies 0.5 g/L as the optimum loading for OH radical formation with a peak at 35.91 µmol/L.…”

“…Over the past several decades, the use of titanium dioxide (TiO 2 , titania) has been increasing significantly due to its advantages and capabilities for various applications, including the antibacterial disinfection of surfaces, self-cleaning and self-sterilization, site remediation, domestic and industrial wastewater treatments [ 1 , 2 , 3 ]. In addition, TiO 2 is highly chemically-stable and human-friendly [ 4 , 5 ], therefore, it can also be used for biomaterials, biomedical devices and food applications [ 6 , 7 ].…”

In this work, metal-doped titanium dioxide (TiO2) was synthesised with the aim of improving photocatalytic degradation and antimicrobial activities; TiO2 was doped with copper (Cu) ranging from 0.1 to 1.0 wt%. The physical and chemical properties of the Cu-doped TiO2 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), the Brunauer–Emmett–Teller method (BET) and diffuse reflection spectroscopy (DRS). The results revealed that the anatase phase of TiO2 was maintained well in all the Cu-doped TiO2 samples. No significant difference in the particle sizes or the specific surface areas was caused by increasing Cu doping. However, the band gap decreased continuously from 3.20 eV for undoped TiO2 to 3.12 eV for 1.0 wt.% Cu-doped TiO2. In addition, the 0.1 wt.% Cu-doped TiO2 displayed a much greater photocatalytic degradation of methylene blue (MB) and excellent antibacterial ability for Escherichia coli (E. coli) compared to undoped TiO2. On the other hand, the high Cu doping levels had negative impacts on the surface charge of nanoparticles and charge transfer for OH• generation, resulting in decreasing MB degradation and E. coli photokilling for 1.0 wt.% Cu-doped TiO2.

“…[ 1 ] Oil spill incidents, such as the 2010 BP‐operated Deepwater Horizon spill in the Gulf of Mexico [ 2 ] , and the 2018 Sanchi oil tanker collision [ 3 ] and subsequent explosions, are another source of environmental pollution that can endanger living species such as sea creatures, birds, [ 1 ] and agriculture. [ 4 ] There is a need to develop efficient methods for the mitigation of oil spills, and this has attracted considerable attention from governments, environmental agencies, and universities.

Effective separation of oil from water is of significant importance globally for various applications such as wastewater treatment, oil spill cleanup, and oil purification. Among the numerous approaches for oil removal, membrane separation is considered one of the most promising approaches due to its selectivity and ease of operation. Electrospinning is a promising technique for producing polymeric membranes with tunable structures with interconnected pores, large surface area, and high porosity. In this study, hydrophobic poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) nanofibrous membranes were electrospun and used for this purpose. The effects of various parameters (e.g., polymer concentration, applied voltage, tip to collector distance, and feed rate) were investigated to find the optimum electrospinning conditions. Further, the electrospun membranes were characterized according to average fiber diameter, morphology, average pore size, and wettability to identify the combinations most likely to succeed in oil–water filtration. The physical–chemical properties of the membranes (i.e., thickness, areal density, porosity, average pore size, water/oil contact angle, hydrostatic pressure head, and oil filtration flux) were studied based on standard test methods. The separation efficiency of eight electrospun membranes with various pore sizes and average fiber diameters were tested for diesel/water mixtures. A linear relation was found between the initial oil flux and the average pore size of the membranes. The maximum oil filtration flux of about 224 L/m2/h, achieving over 75% oil recovery in 10 min, was obtained for the electrospun membrane with the average pore size of 4.5 μm. The membranes were successfully used for eight consecutive oil–water separation cycles without noticeable loss of flux.
