Tin-glycerate (Sn-Gly) spheres were synthesized through a simple solvothermal strategy, which was further thermally converted into SnO2. It is found that the loose SnO(2)spheres have been built up from nanoparticles with about 10 nm in size. The use of such SnO(2)nanostructures was further performed for low-ppm-level acetone detection. The results showed that the SnO(2)presented response of 123 to 100 ppm acetone vapor at 260 degrees C. The sensor also exhibited rapid response/recovery time (24.5 s/6.5 s), low detection limit (1.5 at 1 ppm), excellent selectivity, and good reproducibility. Especially, a good linearity ranging from 1 to 100 ppm acetone was fitted, making it a promising candidate for acetone detection.
