Adsorption and Photocatalytic Degradation of Methylene Blue on TiO₂ Thin Films Impregnated with Anderson-Evans Al-Polyoxometalates: Experimental and DFT Study.

ABSTRACT: In this work, we fabricated a TiO₂ thin film, and the same film was modified with an Anderson aluminum polyoxometalate (TiO₂-AlPOM). Physical-chemical characterization of the catalysts showed a significant change in morphological and optical properties of the TiO₂ thin films after surface modification. We applied the kinetic and isothermal models to the methylene blue (MB) adsorption process on both catalysts. The pseudo-second order model was the best fitting model for the kinetic results; qe (mg/g) was 11.9 for TiO₂ thin films and 14.6 for TiO₂-AlPOM thin films, and k₂ (g mg^-1 min^-1) was 16.3 × 10^-2 for TiO₂ thin films and 28.2 × 10^-2 for TiO₂-
