“…As shown in Figure f, the absorption peak located at approximately 1040 cm –1 can be attributed to the ν3 vibrations of the radical P–O antysym . The absorbance bands at approximately 614 and 539 cm –1 are assigned to the Sn–O and Sn–O-Sn vibration …”

“…30 The absorbance bands at approximately 614 and 539 cm −1 are assigned to the Sn−O and Sn−O-Sn vibration. 31 Because of its rich and strong electron-accepting ability, a more negative charge state site could be formed by the phosphorous-containing oxyanion, which could enable the electron loss of Sn and C and thus induce a strong interaction toward SnO x and carbon. 32 The Raman spectra of SnO 2 /C and P-SnO x /C composites were then analyzed to verify the improved interaction between SnO x and the carbon phase, as shown in Figure 1g.…”

Carbon materials with well-dispersed SnO x particles exhibit excellent lithium-storage performance. However, the volume change of SnO x and the weak interaction between SnO x and carbon induce an unsteady SnO x –C interface during the lithiation/delithiation process. This phenomenon results in enhanced charge transfer resistance and reduced electrical contact of active materials, which leads to low reversibility of tin oxidation, restricted capacity, sluggish kinetics, structural deterioration, and rapid capacity decay. Herein, tin oxide/carbon composites with a metaphosphate-bridged interface are synthesized to construct a robust interfacial contact between tin oxides and carbon. The metaphosphate group functions as a bridge between SnO x and carbon and results in excellent electrochemical stability during the charge/discharge process, which is favorable for electrode structural integrity. The formation of the metaphosphate-bridged interface provides a steady transport channel for e–/Li+ and thus improves the reversibility of the conversion reaction. The enhanced charge transfer and interaction can also boost the charge transfer between SnO x and carbon, which leads to higher SnO x utilization. Thus, the prepared P-SnO x /C anode exhibits enhanced lithium-storage performance in terms of specific capacity, cycling stability, and rate performance.

We have proposed a high selectivity isopropanol gas sensor. The sensor shows significant resistance change only to isopropanol gas. The synthesis method of flower-like SnO2 nanostructures, the electrode material and design, and the optimized working temperature provide the high selectivity and high response of the sensor. The SnO2 nanoflowers have been synthesized in a two-step process as the gas sensitive layer. The sensor shows its best performance on Au interdigitated electrodes. The optimized working temperature is obtained at 150℃. The proposed sensor has a high sensitivity, good repeatability, long-term stability and remarkable selectivity. The responses of the sensor to 100 ppm of isopropanol at 150℃ is 71 and the sensor is capable of keeping almost 96% of the initial response in a 40 days period.
