Double-layered films of TiO2 and activated carbon were fabricated on aluminum substrates by electrophoretic deposition. Moreover, TiO2 powder was synthesized by solvothermal process. The photocatalytic efficiency and reusability of the resulting films were tested for the photodegradation of methylene blue under ultraviolet irradiation. The double-layered films obtained using the synthesized TiO2 exhibited the highest photodegradation efficiency (94%) for removing methylene blue. The immobilized film could solve the problem of separation and recovery of powder catalyst in practical applications. Therefore, the imobilized systems are an advantage for wastewater treatment because they are cost-effective, eco-friendly and reusable with relatively high photocatalytic performance..
