TiO2 nanorods were fabricated on fluorine doped tin oxide (FTO) substrate by hydrothermal method. The hydrothermal solution was prepared with titanium but -oxide, hydrochloric acid and deionized water (volume ratio 1:30:30). The morphologies and structure of the samples were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). Highly ordered and homogenous TiO2 nanorods obtained has a diameter of ca. 100 nm. Gas sensing properties of these structures were investigated against VOCs and different concentrations of H-2 at 200 degrees C. Sensor response was 200 (%) for 1000 ppm H-2. Among measured VOCs, TiO2 nanorods are only sensitive to isopropanol at 200 degrees C. (C) 2015 The Authors. Published by Elsevier Ltd.
