Manoharan et al, 2018 Hoang et al, 2016 cantly capable of increasing speci c surface areas compared to commercial TiO 2 (P25). The higher the speci c surface area of the photocatalyst the higher the area that opens between UV-C rays and the catalyst so as increase photo-active of the catalyst.…”

Silica has become a popular material due to its high abundance and many advantages in various fields. This material can be produced synthetically and extracted from nature with resultant advantages in the application of green production. Therefore, this article deals with the form of silica extracted from quartz sand, leaves, and agricultural wastes found in nature. The extraction process from various sources would be described using thermal, biological, and chemical methods. This review also highlights the potential application of silica as a photo catalytic antibacterial-supporting material and discusses its role in increasing the effectiveness of the process. The discussion was continued with research on this procedure, where synthetic auxiliary materials were compared to the extracted silica. Furthermore, results obtained indicated that the extracted material had very good potential as a photocatalyst adjunct in its application in the antibacterial field.

Textile industry waste can pollute the aquatic environment because it contains dye contaminants with very stable properties that are difficult to degrade naturally. However, dye contaminants degradation can be carried out by photodegradation using ZnO-Fe3O4 magnetic nanocomposite photocatalysts. This study aims to synthesize ZnO-Fe3O4 magnetic nanocomposite through a sonochemical method. Then measure their photocatalytic activity in methylene blue degradation. The best ZnO-Fe3O4 magnetic nanocomposite is made of ZnO:Fe3O4 mass ratio of 4:1 with a crystal size of 31.058 nm, a hexagonal crystal phase and a particle size of 173.23 nm. The ZnO-Fe3O4 magnetic nanocomposites (4:1) provides optimum degradation capacity of methylene blue under halogen lamp irradiation of 99.56 mg/g at pH 13. Furthermore, the ZnO-Fe3O4 magnetic nanocomposites had good stability in 10 cycles reaction with a degradation capacity of 99.24-99.75 mg/g. The photocatalytic degradation of methylene blue by ZnO-Fe3O4 occurs through the formation of free radical species with hydroxyl radicals as the dominant species that play an important role in the degradation process.

“…Each fabric sample was scanned five times for this purpose, and the average was recorded. Standard UPF protection rating in the range of 40-50 and >50 is considered excellent for fabrics, thereby providing effective protection against harmful UV radiation [45]. The UPF value of the pristine cotton fabric was 6, and the values for the fabric treated with functionalised TiO 2 nanoparticles exhibited higher UPF than untreated fabrics due to the ability of nano titania to block UV rays by absorption and scattering.…”

Synthesis and modification of nanoparticles to make them suitable to functionalise a substrate for various application fields involves many steps, which are complex, time-consuming, and sometimes require special equipment. This is a major drawback to meet rapid technological requirements. In this work, a procedure has been developed to modify TiO2 nanoparticles by the sol-gel method at their synthesis stage using titanium tetraisopropoxide and modifying agents including ODS and GPTMS. The prepared nanoparticle finish can be used as it is without any further processing, thus eliminating the need for extra steps required to decorate them on some substrate. The nanoparticles were characterised by SEM, EDX, FTIR, XRD, and zeta potential. The adhesion of the obtained nanoparticles was tested by applying them to a cellulosic substrate. The obtained substrate was subjected to mechanical action and adhesion efficiency was estimated on the basis of UV transmittance and antibacterial properties that showed excellent results. The hydrophobic properties of the obtained nanoparticles were assessed by measuring water contact angles, which reached 157.9°, indicating their superhydrophobic nature. The developed procedure is facile and will be suitable for the engineering of multiple surfaces.
