2021年11月19日 · XRD, Raman, FTIR, XPS and SAED analysis revealed a crystalline hybrid structure of Ag core and Ag 2 O shell. Besides, SEM and HRTEM micrographs depicted spherical nanoparticles with size...

Ag纳米颗粒平均尺寸为5nm， 高分辨快速傅里叶变化 显示存在(220)、(111)晶面，与 XRD 结果对应。Ag纳米颗粒周围有明显的CNTs管壁缺失，表明Ag颗粒深嵌入CNTs。

2015年9月1日 · Recently, it has been shown that a heterostructure type Ag–Ag 2 O/TiO 2, synthesized by a simple electrochemical method, resulted in a high active and stable photocatalyst under visible light, following a Z-scheme charge transfer mechanism [25].

2022年3月1日 · HRTEM, XPS analysis shows that the photocatalyst has a large sheet-like morphology with well-dispersed small metallic Ag particles (<3 nm) on the WO3 nanoparticle's surface, with most particles near the edges. Ultraviolet–visible spectra analysis observed a large redshift in the absorbing band edge and decreased bandgap energy from 2.6 to 2.1 eV.

2020年11月15日 · To improve the catalytic activity of cerium (IV) oxide (CeO 2), in this study, we introduced silver (Ag) into this compound hydrothermally to form Ag/CeO 2 nanocomposites with molar ratios 1:1, 1:2, and 1:3. We also used the hydrothermal method to add various graphene contents (3, 5, and 10 wt%) to the optimum Ag/CeO 2 catalyst.

We found that a conducting Ag 2 S argentite phase and a Ag nanocrystal together formed the ionic and electronic conductive channel. The preferential atomic sites for Ag nanocrystal growth within the argentite phase were finally clarified.

2016年9月17日 · HRTEM images of region of transition between Ag and Ag 2 S for off-state a and on-state b of Ag 2 S/Ag heteronanostructure. The Pt electrode is located on the top part of the image, and Ag electrode is in the bottom part.

Download scientific diagram | The XRD patterns and HRTEM images of Ag2S/Ag heteronanostructures. The long and short ticks on XRD patterns correspond to reflections of …

2009年7月15日 · The starch-stabilized Ag nanoparticles were successfully synthesized via a reduction approach and characterized with SPR UV/Vis spectroscopy, TEM, and HRTEM. By utilizing the redox reaction between Ag nanoparticles and Hg2+, and the resulted decrease in UV/Vis signal, we develop a colorimetric method for detection of Hg2+ion.

The crystal structure of the superconducting−superionic conducting nanohybrid, Ag 1.17 I 1.54 Bi 2 Sr 2 CaCu 2 O y, has been investigated by performing high-resolution transmission electron microscopy (HRTEM) and micro-Raman spectroscopy.
