Abstract

A series of photocatalytic TiO₂ membrane was prepared on macroporous Al₂O₃ support via sol–gel route using polymer templates including Pluronic block copolymers of P123, F127 and poly(vinyl chloride) (PVC) homopolymer. The TiO₂ layer on Al₂O₃ support reduced permeability due to pore size reduction regardless of polymers applied. The TiO₂/Al₂O₃ composite membrane under UV light reduced organic fouling. The PVC based-homopolymer showed highest adsorption capacity and catalytic function with TiO₂/Al₂O₃ composite membrane. Organic removal efficiency of 95% was achieved by PVC based TiO₂/Al₂O₃ composite membrane. The precoating with the PVC polymer template led to uniform TiO₂ film by mitigating pore infiltration.
