TiO<sub>2</sub>‑based gas sensors have attracted significant attention in past decades due to their excellent physical/chemical properties, low cost and high abundance on Earth. In recent years, more and more efforts have been invested for the further improvement in sensing properties of TiO<sub>2</sub> by implementing new strategies such as growth of TiO<sub>2</sub> in different morphologies.
