摘要：
Porous Co3O4 nanorods are fabricated using facile hydrothermal method from CoCl2·6H2O and CO(NH2)2, and further modified with SnO2 nanocrystals through a self-assemblies route. The effects of self-assembling SnO2 onto porous Co3O4 nanorods sensing properties were investigated. The gas-sensing measurements show that after assembling SnO2 nanocrystals onto the surface of porous Co3O4 nanorods, the gas sensing properties of the sensors toward CH3CH2OH and H2S were greatly improved, and the detection limits of CH3CH2OH and H2S were reached 5.0×10-6 and 1.0×10-6, respectively.
