Abstract

The novel sensors based on TiO2 nanotubes-supported MS (TiO2@MS, M = Cd, Zn) are synthesized via a simple wet chemical method at room temperature. The products are characterized with transmission electron microscopy (TEM), X-ray diffraction (XRD), and photoluminescence spectrum (PL). Their optical and morphological properties indicate the interaction between the TiO2 nanotube and MS nanoparticle. The gas-sensing properties of the obtained samples are studied. Sensors based on the TiO2@MS core/shell heterostructures all show improved gas-sensing properties. The results reveal that the improved performance of the nanocomposites strongly depends on the specific interaction between MS and support.
