Facile synthesis and immobilization of Ag-TiO2 nanoparticles on electrospun PU nanofibers by polyol technique and simple immersion

► One-pot polyol method led to synthesis of Ag NPs deposited on TiO2 NP substrate. ► The synthesized Ag-TiO2 NPs were decorated on electrospun PU mat by simple immersion. ► Well-dispersed Ag-TiO2 NPs were found to be strongly adhered on the PU surface. ► The Ag-TiO2 NP-decorated PU composite mat showed superior photocatalytic efficiency. ► The present composite mat could have potential use in water treatment application.
