Photocatalytic membranes as water decontamination agents

Water contamination by various species, including heavy metals, dust, dyes, pesticides, pathogens, and organic and inorganic substances, poses a stern hazard to health of the human and environment. Various conventional methods for decontamination and improving water quality are practical; most are however, inadequate, less effective, time-consuming and expensive. Photocatalytic membranes (PMs) technology with light-sensitive functionalities can be efficiently used to remove noxious pollutants from aqueous systems, thereby reducing operational costs and environmental impact. This review focuses the fundamentals of PM function, current developments in material synthesis, and the potential of green synthetic methods to develop sustainable PMs for sustainable future. Because of their high efficiency and minimal environmental impact, these technologies offer a promising solution to the pressing need for efficient water filtration in urban and industrial settings.
