Abstract
A novel catalytic film of Fe2O3/UiO-66-NO2/TFC-PA was successfully synthesized via the conventional polymerization technique. The as-fabricated sample was characterized by XRD, FT-IR, UV-Vis DRS, and N2 adsorption-desorption isotherm. The catalytic activity of the film was examined by degradation of Methylene blue (MB) under irradiation of visible light. The synthesis conditions of the film were studied as well. The results illustrated that under optimal synthesis conditions as the Fe2O3/UiO-66-NO2 amount of 0.01 g, the polymerization time of 30 s, the catalytic particles were dispersed in the TMC solution and the TMC concentration was 0.1%, the film exhibited a MB removal percentage of 95 %. The material also showed an outstanding regenerative performance with the treatment efficiency reaching 92.8% after four regenerations. The kinetic results showed that the photocatalytic degradation of MB over the film followed the first-order kinetic model.
