Abstract

Selectivity is still a major problem in gas sensors. In this study, we fabricated a novel sensor material, tin oxide (SnO2) nanoparticle decorated tin selenide (SnSe) nanosheets (SnO2/SnSe), via a simple solvothermal method. SnO2 nanoparticles of size ∼10 nm were anchored on the surface of SnSe nanosheets. The gas-sensing performances of SnO2/SnSe composites calcined at different temperatures were compared. Methylbenzene-sensing performance analysis performed at different temperatures and concentrations showed that SnO2/SnSe composites exhibited preferable sensitivity, excellent selectivity, and a good response rate. The improved sensing properties, especially the selectivity, are attributed to the appropriate heterojunction of SnO2 nanoparticle decorated SnSe nanosheets.
