Project title: Hybrid membrane Vis–LED photoreactor for simultaneous pharmaceuticals degradation and photocatalysts separation
Project short description: In recent years, TiO2–assisted photocatalysis has become a potentially cost–effective and environmentally–sustainable treatment technology for water reclamation and reuse. However, TiO2 could be photoexcited only under UV irradiation due to its large band gap which hampers its commercial–scale application. In addition, the key challenge for applying the TiO2 suspension system is that the TiO2 particles have to be separated from the product water. This study therefore focused on (1) developing visible–light responsive TiO2–based photocatalysts for photocatalytic degradation of pharmaceuticals under visible–light irradiation, and (2) developing hybrid membrane photoreactor (MPR) systems for photocatalyst recovery and reuse in the photoreactor.
