In the current study, we report the development of Titanium Dioxide nanorods (TiO<inf>2</inf> NRs) rutile phase on NiTi alloy using a chemical vapor deposition technique. Systematic studies were performed for different camphor quantity (ranging from 3 mg to 7 mg) along with a constant substrate temperature at 950 °C. TiO<inf>2</inf> NRs formation at a particular substrate temperature, controlled by the solid camphor precursor, results in dominant rutile phases of TiO<inf>2</inf> within the nanorods (NRs) which was confirmed from X-ray diffraction. Off-normal growth with varying rod diameter and efficient photocatalytic properties are characteristics of these NRs prepared with the proposed method. Field-effect scanning electron microscopy (FE-SEM) revealed TiO<inf>2</inf> NRs with exceptionally long length and diameter of 5-7 μm and 60-100 nm, respectively. The presence of oxygen in the camphor under argon and hydrogen atmosphere and assisted by nickel, results in thinning and elongation of the NRs. The resulting TiO<inf>2</inf> NRs exhibited high crystallinity and large surface areas with high refractive Index, which is one of the promising materials for energy conversion applications.falseCamphor | Chemical vapor deposition | Energy Conversion | FE-SEM | Raman Spectroscopy | Shape Memory NiTi (alloy) | TiO2 nanorods | X-Ray DiffractionConference Paper22147853475-479201940Conference PaperConference Paper33
