Abstract

Titanium oxide supported palladium (TiO₂/Pd) and titanium oxide supported platinum (TiO₂/Pt) nanoparticles were prepared from their precursors through the incipient wetness method. The TiO₂/Pd and TiO₂/Pt nanoparticles were characterized by scanning electron microscopy (SEM), and energy dispersive X-rays (EDX), while the photodegradation study of methyl violet was performed by UV/VIS spectrophotometry. The morphological study shows that the Pd and Pt were well deposited on the surface of TiO₂, which was confirmed by EDX. Both TiO₂/Pd and TiO₂/Pt nanoparticles were used as photocatalysts for the photodegradation of methyl violet in aqueous media under UV-light irradiation. The photodegradation study revealed that the TiO₂/Pd and TiO₂/Pt nanoparticles degraded about 95 and 78% of dye within 20 min, respectively. The effect of various parameters such as catalyst dosage, concentration of dye, and medium on the photocatalytic degradation was examined. The activity of recovered TiO₂/Pd and TiO₂/Pt nanoparticles was studied.
