Synthesis of self-assembled hollow spherical Au/SnO2@rGO and its enhanced hydrogen sensing properties to ppb-level

Achieving One Part Per Billion Hydrogen Sulfide (H2S) Level Detection through Optimizing Composition and Crystallinity of Gold-Decorated Tungsten Trioxide (Au-WO3) Nanofibers

“…The interplanar spacing calculation based on selected regions are shown in Figure b–d. The interplanar spacing of 0.377 and 0.367 nm can be assigned to the (020) and (200) planes of monoclinic WO 3 , which matches with results from previous literature. – Meanwhile, an interplanar spacing of 0.236 nm confirms that the cubic Au was decorated on the WO 3 nanofiber surface. , Figure e reveals the selected area electron diffraction (SAED) pattern of S12, which suggests a polycrystalline structure. Figure f–h represents the elemental mapping of S10, S11, and S12, respectively.…”

Ultra-effective room temperature gas discrimination based on monolithic Pd@MOF-derived porous nanocomposites: an exclusive scheme with photoexcitation

“…5f is deconvoluted into two peaks around 530.24 eV and 531.49 eV, which are assigned to the lattice oxygen (O lat ) and adsorbed oxygen (O ads ), respectively. 61 The ratio of O ads /O lat increases first and then decreases with the increase of Pd content, which is caused by the significant effect of different states of Pd on oxygen species. The higher relative intensity of O ads at lower Pd molar ratios ( x ≤ 2.5) may be attributed to the adsorption of oxygen species, which could be enhanced by the Pd in the lattice.…”

Development of p-n Heterostructures Using Phosphorene and SnO2: Its Efficacy toward the Adsorption Study of CO2 and Rose Bengal Dye

“…The obtained solution was then autoclaved for 24 h at 175 °C in a hot air oven, and finally, it was centrifuged and washed several times with ethanol and water to remove all the impurities. The obtained product was dried at 60 °C for 12 h. The pure SnO 2 was calcinated at 400 °C for 4 h with a heating rate of about 5 °C/min …”

“…The obtained product was dried at 60 °C for 12 h. The pure SnO 2 was calcinated at 400 °C for 4 h with a heating rate of about 5 °C/min. 27 Synthesis of Ph@SnO 2 . After the successful synthesis of Ph nanosheets and SnO 2 , Ph@SnO 2 has been prepared by adopting the same aforementioned procedure as shown in Scheme 1.…”
