Wet Chemical Synthesis of Reduced TiO۲ Nanorods for Solar Harvesting Applications

This study investigates a wet chemical synthesis method for producing reduced TiO۲ nanorods (TiO۲-x) to enhance solar energy harvesting efficiency. TiO۲ nanorods were synthesized via the hydrothermal method and reduced using a chemical reducing agent. XRD and SEM analyses confirmed the formation of the anatase phase with rod-like nanostructures. UV-Vis spectroscopy demonstrated significant visible light absorption (۴۰۰-۷۰۰ nm) due to the formation of Ti³+ states and oxygen vacancies. Photocatalytic evaluation under visible light showed ۸۵% degradation of methylene blue dye within ۱۲۰ minutes, representing substantial improvement compared to pristine TiO۲. These results indicate the high potential of wet-chemically synthesized TiO۲-x nanorods for solar energy applications.
