Abstract
We report the microstructures and gas sensing properties of two novel SnO2 nanorods prepared by hydrothermal method with the utilizing of cetyltrimethylammonium bromide and polyethylene glycol. The structures and morphologies of the dense and porous nanorods were characterized by means of powder X-ray diffraction and scanning electron microscopy. The gas sensing performances towards ethanol of the two samples were investigated. The results show that the porous SnO2 nanorods display excellent gas response to ethanol, indicating SnO2 as a potential gas sensing material for broad applications.
