Abstract

Porous TiO₂ films are widely used in photocatalysis for pollutant remediation and synthetic chemistry applications, and the homogeneity and stability of the films are important parameters. Here, we show that porous TiO₂ and Fe-doped TiO₂ (Fe-TiO₂) films on Ti foils with homogeneous structure and well-controlled doping can be synthesized by a cooling enhanced plasma electrolytic oxidation (CPEO) method. The anatase content within pristine TiO₂ films and the concentration of Fe dopant in Fe-TiO₂ films can be manipulated by simply adjusting the synthetic parameters, leading to an optimum photocatalytic performance under both UV and visible light irradiation for the decomposition of methylene blue.
