Harnessing the impact of TiO۲ nanotubes, TiO۲ nanofibers and their incorporation in polysulfone composite membrane for the photocatalytic degradation of reactive black ۵

Most water resources today are contaminated for various reasons. Examples are dyes that pollute aquatic systems and threaten the environment. To overcome this problem, photocatalytic decomposition is a prominent method for eradicating hazardous dyes from water. The hydrothermal synthesis of TiO۲ nanotubes and nanofibers and their subsequent utility in degrading Reactive Black (RB) ۵ dye is of great interest, and the resulting nanomaterials have been characterized and validated via various techniques: ultraviolet visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy dispersive analysis (EDAX). Polysulfone (PSF) composite membranes lodged with synthesized nanomaterials were tested for the degradation of RB ۵ dye. As a result, dye degradation of ۸۹.۸% and ۸۰.۲% was achieved with the TiO۲ nanofibers and TiO۲ nanotubes, respectively. When the nanomaterials were allowed to act upon the dye solution alone, the TiO۲ nanofibers degraded up to ۴۸.۷%, whereas the TiO۲ nanotubes degraded up to ۱۸.۶% because the strength of the nanomaterials was not enough for dye decomposition. This study reports on the synthesis and characterization of nanomaterials, as well as their combination for an enhanced dye degradation process.
