In the present study, N–TiO2–P25 nanoparticles were synthesized by a modified sol–gel method under different nitrogen concentrations, calcination temperature, and stirring time, and their morphology and characteristics were studied by XRD, SEM, XPS, BET, and CHNOS elemental analyses. The results exhibited changes in structural properties of the as-prepared nanoparticles by varying these synthetic parameters. The response surface methodology based on the central composite design was used to optimize the synthesis parameters in photodegradation of Acid Red 73 under visible light irradiation. The optimal value identified for preparation of N–TiO2–P25 was found to be a urea/TTIP molar ratio of 2.95, a calcination temperature of 400 °C, and a stirring time of 375 min. Under optimal synthesis conditions, the N–TiO2–P25 film was coated on reticulated alumina foam and its structural properties were characterized by XRD, FESEM, BET, and UV–Vis diffuse reflectance spectroscopy techniques. The synergistic effect of P-25 incorporation and N doping led to the higher Vis activity of N–TiO2–P25 films compared with those of the films modified with nitrogen or P-25 powders only. The reusability and reasonable photocatalytic performance of the as-prepared film leads to considering it as an alternative for large-scale applications of water treatment.
