“…Several studies have addressed these two issues and made some progress. On the one hand, chemical doping is widely used to achieve visible-light-induced PIH effect. − Fe 3+ , a kind of transition metal ions, is widely used as dopant because its radius (0.64 Å) is close to Ti 4+ (0.68 Å), which is beneficial for the cation substitution process . It can improve the photocatalytic activity of TiO 2 with a low doping concentration .…”

Based on the superhydrophilicity of titanium dioxide (TiO 2 ) after ultraviolet irradiation, it has a high potential in the application of antifogging. However, a durable superhydrophilic state and a broader photoresponse range are necessary. Considering the enhancement of the photoresponse of TiO 2 , doping is an effective method to prolong the superhydrophilic state. In this paper, a Fe 3+ doped TiO 2 film with long-lasting superhydrophilicity and antifogging is prepared by sol−gel method. The experiment and density-functional theory (DFT) calculations are performed to investigate the antifogging performance and the underlying microscopic mechanism of Fe 3+ doped TiO 2 . Antifogging tests demonstrate that 1.0 mol % Fe 3+ doping leads to durable antifogging performance which lasts 60 days. The DFT calculations reveal that the Fe 3+ doping can both increase the photolysis ability of TiO 2 under sunlight exposure and enhance the stability of the hydroxyl adsorbate on TiO 2 surface, which are the main reasons for a longlasting superhydrophilicity of TiO 2 after sunlight exposure.
