In this document, the photocatalytic activity of TiO/FeO, prepared by the mixing of the pure oxides, was studied. The photocatalytic degradation of aqueous Methylene Blue (MB) solutions (10 and 30 ppm) was performed, the TiO/FeO catalysts in 80/20, 50/50 and 20/80 mass ratios were used during the test, artificial sunlight and natural solar radiation were tested at laboratory and pilot plant scale respectively. Besides, the kinetic reactions were evaluated according to the Langmuir-Hinshelwood model, the apparent velocity constants (k) were obtained for the TiO/FeO catalysts. In the laboratory test, the TiO/FeO catalyst (80/20) had a performance for 93.04% of discoloration, k = 0.0238 min, while for TiO/FeO (50/50, 20/80) had an 83.46%, 65.00% for discoloration of MB and the k values were 0.0154 min and 0.0098 min, respectively. In the solar test at pilot scale, the percentages of discoloration of 24.32%, and 57.78%, with k values of 0.00037 min, 0.00121 min respectively were obtained for TiO/FeO (80/20), a MB solution of 30 ppm, a load of 0.1 g/L and 0.3 g/L of the catalyst respectively.
