A nanostructured Rh/RhO 2 mixture was easily obtained by thermal treatment of the macromolecular chitosan·(RhCl 3 ) X precursor, while the pure Rh 2 O 3 was obtained from pyrolysis of the PSP-4...

2024年11月4日 · In this work, the volumetric compression of Rh at ambient T has been investigated experimentally under quasi-hydrostatic conditions using a combination of synchrotron XRD and DAC with He as PTM...

2023年3月14日 · The crystal structure of the as-obtained Rh-RuO 2 /G was validated by X-ray diffraction (XRD) pattern (Fig. 2a), in which three prominent broadened diffraction peaks are well matched with the...

These catalysts were characterized by inductively coupled plasma-optical emission spectroscopy (ICP-OES), N2 adsorption–desorption, X-ray diffraction (XRD), transmission electron microscopy (TEM...

2023年11月1日 · Various characterization techniques can be employed to study the structure of IMCs, including XRD, selected area electron diffraction (SAED), and AC-HAADF-STEM. XRD is a commonly used technique to determine the crystal structure of IMCs.

The high resolution Rh 3d XPS spectrum displays the two prominent peaks at 307.4 and 312.1 eV, corresponding to the 3d 5/2 and 3d 3/2 peaks of metallic Rh, respectively.

At ambient conditions, Rh presents a face centred cubic (fcc) structure, that was shown to be stable up to at least 200 GPa at ambient T via a single-shock experiment10. Such a phase stability at ambient T was also confirmed up to 150 GPa by X-ray diffraction experiments (XRD) performed with diamond anvil cells (DAC)

2025年3月31日 · 1.0Rh/TiO₂样品：图像则显示了Rh簇和小颗粒的出现（黄色标记）。随着Rh负载量的增加，铑的分散程度减弱，簇状和小颗粒状的Rh开始显现。 通过观察不同Rh负载量对TiO₂表面铑分散状态的影响，能够推测Rh分散状态与催化性能之间的关系。

1 天前 · To further understand the influence of Tm 3+ ions on phase stability of CsPbI 2 Br thin films, we examined the XRD pattern of the control and 0.75 % Tm-doped thin films with varying aging periods under ambient conditions (40 ± 5 % RH) at room temperature without encapsulation and nitrogen gas.

我们报告了在受控温度和相对湿度条件下使用 X 射线衍射 (RH-XRD) 来研究潜在有害的相变反应。 基于速率测量的改进程序用于准确和可重复地确定潮解和水合反应的平衡湿度。 使用这种改进的 RH-XRD 技术测定的 NaCl (75.4+/-0.5% RH) 和 Ca (NO3)2 x 4 H2O (50.8+/-0.7% RH) 在 25 摄氏度的潮解湿度与现有的文献资料。 对无水 Ca (NO3)2 水合形成 Ca (NO3)2 x 2 H2O 的测量显示平衡湿度为 10.2+/-0.3%，这也与现有数据合理一致。 总之，动态 X 射线衍射测量是准确和精 …
