The increasing spread of persistent organic contaminants in wastewater represents a matter of environmental and public health relevance, with direct implications for human health. In this context, the integration of photocatalysis with membrane filtration represents a particularly promising approach for the removal of organic pollutants, as it combines physical separation and chemical inactivation within a single functional system. The present thesis work is aimed at the design, fabrication, and characterization of photocatalytic nanofibrous membranes produced by electrospinning. Nanofibrous membranes based on styrene–butadiene rubber (SBR) were developed via suspension electrospinning and subsequently stabilized through UV-induced thiol–ene crosslinking, in order to improve their structural and chemical stability in aqueous environments.
