Resumen

Powder samples (P) of TiO₂ and Pt/TiO₂ were prepared using conventional methods. Then, thin films (TF) incorporating these powders onto SiO₂ films were prepared via dip coating. The powder and thin film samples were characterized by Raman spectroscopy, FESEM, elemental mapping, ICP-OES, HRTEM, UV–vis DRS, and XPS. The samples were then tested in a water-splitting reaction to generate hydrogen, using a water/methanol mixture with a 1:1 volume ratio, and two purple lamps as the radiation sources. The results suggest that incorporating the powder photocatalyst into the thin film resulted in a significant improvement in photocatalytic performance. Furthermore, the thin film samples were more stable during three consecutive runs.
