Synthesis and Investigation of Photocurrent of Titanium Dioxide Nanorods

In this work, titanium dioxide (TiO₂) nanorods obtained by hydrothermal synthesis are studied. Nanowires have proven to be a highly efficient photocatalyst compared to nanoparticles and have an attractive option for their replacement. The use of TiO₂ in the modification of nanorods is important for increasing its photocatalytic activity, as well as improving its mechanical, electrical and optoelectronic characteristics. In the course of the study, TiO₂ nanorods were obtained, which were subjected to structural analysis using scanning electron microscopy. The absorption spectra and photoinduced current of TiO₂ nanorods were also studied. Absorption spectra show that HC tio₂ absorbs in the near ultraviolet region in the range from 300 to 400 nm. Photovoltaic characteristics show that TiO₂ nanorods have a photoinduced current value of about 600 mA. The results obtained open up prospects for the development of highly efficient materials based on TiO₂ nanorods with improved functional properties used in the field of detection, water purification, solar energy and sensors.
