Bimetallic PtAu-Decorated SnO₂ Nanospheres Exhibiting Enhanced Gas Sensitivity for Ppb-Level Acetone Detection.

ABSTRACT: Acetone is a biomarker found in the expired air of patients suffering from diabetes. Therefore, early and accurate detection of its concentration in the breath of such patients is extremely important. We prepared Tin(IV) oxide (SnO₂) nanospheres via hydrothermal treatment and then decorated them with bimetallic PtAu nanoparticles (NPs) employing the approach of in situ reduction. The topology, elemental composition, as well as crystal structure of the prepared materials were studied via field emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The findings revealed that bimetallic PtAu-decorated SnO₂ nanospheres (PtAu/SnO₂) were effectively synthesized as well as PtAu NPs evenly d
