The as-prepared four arm Ag2S zig-zag electrodes exhibited superior optical absorption, as well as photocurrent density of 3.04 mA/cm2 (at 1 V vs Ag/AgCl), compared to one arm Ag2S nanorods...

XPS Spectra Sulfur (S) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.

2021年1月1日 · The XPS analysis of Ag 2 S NPs showed significant Ag 3d peaks (Ag 3d 3/2 at 374 eV and Ag 3d 5/2 at 367.8 eV) and the characteristic peak of S 2p 3/2 at 160.6 eV corresponding to the binding energy of Ag–S.

2022年1月20日 · X-ray photoelectron spectroscopy (XPS) was performed on a SPECS PHOIBOS 150 9MCD by irradiating with an Al Ka source, a pass energy of 75 eV for survey spectra, and 25 eV for core level spectra. The Shirley baseline was …

When tested as an electrode material in three-cell configuration, α-Ag2S electrode shows excellent rate performance (286.2 C g−1 at a scan rate of 2 mV s−1) with superior cycle life (~91%...

XPS analysis confirmed that on the surface of the polypropylene film, a layer of Ag 2 S was formed. ATR-FTIR and FTIR spectra analysis showed that the surface of Ag 2 S layers is slightly oxidized. All prepared layers gave multiple XRD reflections, …

In this paper, we present the results on photoinduced formation of colloidal Ag2S quantum dots with sizes of 1.5–3 nm passivated by 2-mercaptopropionic acid (Ag2S/2-MPA) in the presence of ...

2020年8月18日 · The Z-scheme BiVO4/Ag/Ag2S photocatalyst was fabricated via a two-step route. The as-prepared samples were characterized by XRD, FE-SEM, HRTEM, XPS and UV-vis diffuse reflectance spectroscopy. The results of PL and photocurrent response tests demonstrate that the ternary BiVO4/Ag/Ag2S composites had a high separati

2021年12月1日 · Here, we report synthesis of Ag 2 S nanostructures of zig-zag geometry to achieve the improved photoelectrochemical (PEC) water splitting response for hydrogen generation. A two-step process was utilized for the fabrication of working electrodes.

xrd谱图表明单斜ag2s。 TEM显示产物为棒状纳米颗粒，平均直径为100 nm，其相应的SAED显示出清晰的衍射点，索引为（120）和（303）；XPS证实了Ag2S的形成，并指示了样品的表面化学计量：Ag：S = 1：0.453。
