Abstract

A novel heterostructure of TiO<sub>2</sub> modified Co<sub>3</sub>O<sub>4</sub> (TiO<sub>2</sub>/Co<sub>3</sub>O<sub>4</sub>) acicular nanowire (NW) arrays has been fabricated. After decoration of TiO<sub>2</sub> the TiO<sub>2</sub>/Co<sub>3</sub>O<sub>4</sub> NW array sensor exhibits a much higher response to ethanol compared with the Co<sub>3</sub>O<sub>4</sub> NW sensor.
