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.
