The sol–gel method is efficient and cost‐effective for synthesizing SnO2 sol, wherein SnO2 nanocrystallites (NCs) are stabilized by electric double‐layer of solvated ions tightly bound to ...

In this study, a novel homemade nano catalyst (manganese oxide (MnO2) over tin (IV) oxide (SnO2)) was used for the first time as an effective catalyst in removing dibenzothiophene (DBT) from ...

We investigated the elemental and phase composition, size, morphology, and Raman and absorbance spectra of the nanoparticles synthesized under different inter-electrode gap voltages and the...

2014年1月24日 · In this work, the SnO 2 nano powder is successfully prepared by sol–gel combustion method and is investigated by FTIR, Laser Raman spectroscopy UV–Vis, and Photoluminescence measurements. Moreover, FT-IR and FT-Raman, NMR, UV and Visible spectra are recorded for bulk SnO 2 for the comparison.

2001年10月15日 · Pd/SnO 2 catalysts are prepared according to original procedures: photodeposition and grafting of a molecular complex; the grafting method leads to highly dispersed PdO which is reduced to well-dispersed Pd upon CO adsorption at r.t., whereas NO gives rise to nitrosyl species mainly adsorbed on ionic Pd.

2014年1月24日 · In this work, pure and singe phase SnO2 Nano powder is successfully prepared by simple sol-gel combustion route. The photo luminescence and XRD measurements are made and compared the geometrical parameters with calculated values. The FT-IR and FT-Raman spectra are recorded and the fundamental freque …

2011年4月30日 · The role of antimony in the SnO 2 is demonstrated by FTIR. It is found that at low Sb concentrations, the Sb ions prefer to substitute Sn 4+ in form of Sb 5+.

This paper reports the sensing response characteristics of rf-sputtered SnO2 thin films (90nm thick) loaded with platinum catalyst cluster of varying thickness (2–20nm) for LPG detection.

2023年7月28日 · FTIR and density functional theory (DFT) calculations are combined to support the attribution of specific IR absorption modes. Our results show that heat (100 °C substrate temperature) and vacuum have only a mild effect on the perovskite surface decomposition.

2011年1月10日 · 在这封信中，我们采用傅里叶变换红外光谱 (ftir) 来研究通过喷雾热解沉积的掺氟 sno2 薄膜。 FTIR 证明了氧空位和氟取代氧的作用。 发现在低掺杂水平下，氟离子更喜欢占据 SnO2 晶格中的氧位置。
