“…Figure 4A is the Sn3d spectrum of the AuNPs-SnO 2 -rGO ternary nanocomposite. As can be seen from the figure, two strong peaks occur at 486.36 and 494.81 eV, attributed to the binding energy of Sn3d 3/2 and Sn3d 5/2 , respectively, indicating the SnO 2 formation (Khlayboonme and Thowladda, 2018; Nguyet et al, 2018). Figure 4B reveals the Au4f spectrum of the AuNPs-SnO 2 -rGO hybrid, confirming the Au presence in the hybrids, with significant signals at 87.6 and 83.36 eV corresponding to metallic Au (Meng et al, 2017).…”

A high-performance sensor for detecting SF 6 decomposition components (H 2 S and SOF 2 ) was fabricated via hydrothermal method using Au nanoparticles/tin oxide/reduced graphene oxide (AuNPs-SnO 2 -reduced graphene oxide [rGO]) hybrid nanomaterials. The sensor has gas-sensing properties that responded and recovered rapidly at a relatively low operating temperature. The structure and micromorphology of the prepared materials were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Raman spectroscopy, energy-dispersive spectroscopy (EDS), and Brunauer-Emmett-Teller (BET). The gas-sensing properties of AuNPs-SnO 2 -rGO hybrid materials were studied by exposure to target gases. Results showed that AuNPs-SnO 2 -rGO sensors had desirable response/recovery time. Compared with pure rGO (210/452 s, 396/748 s) and SnO 2 /rGO (308/448 s, 302/467 s), the response/recovery time ratios of AuNPs-SnO 2 -rGO sensors for 50 ppm H 2 S and 50 ppm SOF 2 at 110°C were 26/35 s and 41/68 s, respectively. Furthermore, the two direction-resistance changes of the AuNPs-SnO 2 -rGO sensor when exposed to H 2 S and SOF 2 gas made this sensor a suitable candidate for selective detection of SF 6 decomposition components. The enhanced sensing performance can be attributed to the heterojunctions with the highly conductive graphene, SnO 2 films and Au nanoparticles.

In this study Cu-doped SnO 2 (Sn 0.98 Cu 0.02 O 2 ) thin film was deposited on the glass substrate by sol-gel dip-coating technique. The structural, morphological, and optical properties of the prepared film were studied by X-ray diffraction (XRD), Optical Microscopy (OM), and Uv-visible spectroscopy respectively. XRD analysis revealed that the structure of our deposited film is hexagonal and the crystallite size is found to be 3.89 nm. The surface morphological studied by (OM) indicates that the film is homogeneous. The result of optical properties shows high transmittance estimated at 73.98% and the optical band gap was found 3.961 eV. The gas sensing properties of the prepared film were examined at different operating temperatures and different volume concentrations of liquefied petroleum gas (LPG). It was found that Cu doped SnO 2 has an excellent response and recovery time for 1.8 vol% LPG at 250 • C, their values are equal to 11s and 19s respectively, obtained sensors presents high selectivity to LPG against H 2 S, NH 3 and CO 2 .
