Abstract
Pristine and different amounts of praseodymium oxide (Pr6O11)-functionalized tin oxide (SnO2) flower-like architectures were synthesized by a facile one-step hydrothermal method. Their crystal structure, surface morphology, and chemical compositions were analyzed by XRD, SEM, TEM, and XPS. Measured results showed that Pr existing was in the form of Pr6O11. Compared with pristine SnO2 architectures, the gas sensing properties toward acetone of Pr6O11-functionalized SnO2 architectures could significantly be enhanced under different working temperatures. The response of the as-synthesized Pr6O11/SnO2 (Pr(mol): Sn(mol) = 1:50) sensor to 100 ppm acetone was about 27, which was about three times higher than that of pristine SnO2 architectures. The response/recovery time was 2/36 s at 200 degrees C. When acetone concentration was down to 1 ppm, Pr6O11/SnO2 (Pr(mol): Sn(mol) = 1:50) sensor also exhibited an obvious response. Meanwhile, the enhanced gas sensing mechanism of Pr6O11-functionalized SnO2 architectures was discussed, and the results indicated that the architectures are promising candidates for the practical acetone sensing.
