Abstract

This study reports the fabrication of a self-cleaning ultrafiltration (UF) membrane with a photocatalytic surface. The photocatalyst TiO₂/a-MoS_x/Ag (TMA) was synthesized by photodeposition and selectively immobilized onto the active layer surface using polydopamine (PDA), a mussel inspired adhesive. When compared to the conventional method of fabricating a mixed matrix membrane, photocatalyst coating by post-processing achieved both hydrophilic modification and a photocatalytic surface without compromising the membrane's integrity. TMA photocatalyst, on the other hand, exhibited enhanced photocatalytic degradation as well as faster self-cleaning performance on the membrane surface.
