Immobilizing a visible light-responsive photocatalyst on a recyclable polymeric composite for floating and suspended applications in water treatment.

ABSTRACT: A visible light responsive TiO₂/Ag₃PO₄ (10 : 1) nanocomposite was prepared and successfully immobilized (12 wt%) in a spherical polymeric matrix consisting of polysulfone and alginate (10 : 6). The resulted beads featured a sponge-like structure with interconnected macrovoids and micropores, and showed high adsorption and visible-light photocatalytic activity towards various wastewater pollutants, including the widely used dye - methylene blue (k = 0.0321 min^-1), and two emerging pharmaceutical contaminants - diclofenac (k = 0.018 min^-1) and triclosan (k = 0.052 min^-1). As determined, the ˙OH radical and h⁺ are the primary reactive oxygen species responsible for the photodegradation. The compo
