- Abstract
A novel room temperature gas sensor based on porous In2O3 nanorods was successfully synthesized via a facile reflux method. The In2O3 demonstrates a rod-like shape with a diameter of 10 - 20 nm and a length about 70 - 100 nm, which displays good and uniform size. Studies have shown that the porous In2O3 nanorods have the n-type semiconductor characteristic. We demonstrate that it can detect NOx gas with a sensitivity of 17, fast response of 17.3 s to 97.0 ppm NOx and a low detection limit of 0.485 ppm at room temperature.
