Synthesis of molybdenum oxide-titanium dioxide nanocomposites with ultrashort laser ablation in water

Nanocomposites of Molybdenum oxide (MoO₃) and Titanium dioxide (TiO₂) were synthesized with femtosecond laser ablation of the pelleted powder in water. The pressing with Cold Isostatic press (CIP) provides facile method for pelletization of the oxides mixture. With this method the nanocomposites can be synthesized without replacement of the target during laser ablation. After laser ablation in water the stable MoO₃-TiO₂ nanocomposites were synthesized. The morphology of the synthesized nanocomposites was investigated with transmission electron microscopy. While the band gap modifications of the synthesized nanocomposites were witnessed with UV-Visible diffuse reflectance spectroscopy analysis. Besides, the generated nanocomposites were used for photovoltaic and photocatalytic applications. The nanocomposites exhibit significant improvement in the rate of photo conversion and photodegradation as well.
