Abstract
In a few past years, finding efficient photocatalysts for direct harvesting and conversion of solar energy into clean hydrogen fuel or photodegradation of environmental pollution is one of the most important strategies to overcome energy constraints and environmental problems. The TiO2 photocatalyst has a high band gap and recombination rate and is active only in the UV range, which is a small part of the sun's spectrum. In order to dominate the limitations of this photocatalyst and improve its optical and electronic properties, many studies have been done, including the doping of various elements to change the energy level and band structure of TiO2. In this project, it was attempted to obtain hydrothermally prepared reduced titanium dioxide nanorods (RTNR) in the presence of hydrogen/ nitrogen gas flow. Reduced TiO2 nanorods have established themselves as a promising photocatalyst due to the creation of oxygen vacancies and surface disorder, consequently, the increase in absorption at visible spectrum and enhancement of the optical properties of the nanostructure.
