Indexing XRD patterns correspond to the face-centered-cubic (FCC) lattice of Pt (JCPDF 04-0802), Pd (JCPDF 46-1043) and PdPt alloy (JCPDF 65-6418) structures. ... ... analysis of the position...

The synthesized Pd nanoparticles have been characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), selective area electron diffraction and energy dispersive analysis by X-rays (EDAX) analyses. XRD analysis indicates the preferential orientation of catalytically active {111} planes in Pd nanoparticles.

In the XRD analysis, five basic peaks attributed to Pd-NPs, and an average crystallite size was 10.31 nm. In addition, SEM and HR-TEM determined that Pd-NPs have a quasi-spherical shape, and...

We investigate the electrochemical behaviour of Pd NPs in the presence of hydrogen over a large range of particle diameters, between 3.8–21.5 nm. The study is carried out in both a...

The XRD and Pd 3d X-ray photo electron spectra of exhibit peaks due to both PdO and metallic Pd after the steady state at 650 °C. These results show PdO releases oxygen and convert to metallic Pd after 500 °C and the NO conversion in this temperature region is mainly due to the Pd–PdO oxidation–reduction cycle.

XRD标准数据库包括 JCPDS （即PDF卡片）, ICSD， CCDC 等，分析XRD谱图的软件包括 Jade，Xpert Highscore等，这里推荐使用 Jade。 在Jade软件中，专门有一个功能叫Identify。 里面的 Search/Match 功能可以将样品的衍射图样与标准谱图进行对比，给出与所测样品相吻合的标准谱图信息。 下图所示，是TiO2样品XRD谱图在Jade软件中的Search/Match操作。 如上图所示，在Jade的Search/Match功能中会给出 标准谱图的衍射条纹，物相名称，化学式，匹配程 …

Pd is Copper structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pd is bonded to twelve equivalent Pd atoms to form a mixture of edge, face, and corner-sharing PdPd12 cuboctahedra.

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

最近的实验遇到了一个问题，我将Pd生长在了载体表面，做XRD能够明显看到在40.1度出现Pd的（111）晶面衍射峰，46.6（200）以及68.1（220）两处的峰不是特别明显（也能看见）。

在 PD 的 XRD 衍射图中，可以观察到几个特征衍射峰，分别对应于晶体中的不同晶面。 其中，最强的衍射峰通常对应于（001）晶面，其次是（101）和（110）晶面。 这些衍射峰的位置与 PD 的晶体结构密切相关，可以用于分析样品的晶体形态和取向。 4.实验条件：XRD 实验中的射线能量、扫描角度、扫描范围等参数也会影响衍射峰位置。 适当调整实验条件，可以优化衍射峰的分辨率和信噪比。 总之，PD 的 XRD 衍射峰位置是一个反映其晶体结构特征的重要参数。 通过对衍 …
