“…Traditional photocatalysis utilizes semiconductor materials, such as metal oxides [10][11][12], perovskite oxides [13,14], and metal chalcogenides [10,15], that are synthesized chemically with the use of potentially toxic reagents. These catalysts are typically also produced in bulk powders or thin films, where surface area and reproducibility concerns arise in terms of large-scale water treatment usage.…”

The controlled manufacturing of semiconductor photocatalysts is crucial to their development for drinking water treatment. In this study, TiO2-coated meltblown nonwoven fabrics prepared via Atomic Layer Deposition (ALD) are applied for the inactivation of Escherichia coli (E. coli). It is observed that in the presence of an ultraviolet light-emitting diode (UV-LED) light source (255 nm), 1.35 log E. coli inactivation is achieved. However, exposure to catalyst-coated fabrics in addition to the light source resulted in >4 log E. coli inactivation, suggesting a much higher rate of hydroxyl radical formation on the surface, leading to cell death.
