层状双（金属）氢氧化物（Layered double hydroxides，简称LDHs）， 是一类具有二维纳米结构的层状材料， 又称 水滑石 、类水滑石或阴离子粘土，主要由带正电的片层和层间阴离子组成。

2018年2月21日 · In this report, we applied in situ transmission electron microscopy (TEM) to extensively characterise the thermal progressions of nickel-iron containing (Ni-Fe) LDH nanomaterials. The combinative...

2021年2月1日 · The XRD patterns of all Mg/Al LDH samples confirmed the presence of hydrotalcite (ICDD #14-0191) (Fig. 2). Characteristic patterns of the hydrotalcite phase were found with the basal reflection in the 7.7–8.1 Å range [8] and subsequent peaks in the range of: 4.04–3.80, 2.61–2.57, 2.35–2.29, 2.01–1.95, 1.54–1.52 and 1.50–1.49 Å.

2020年1月1日 · In this chapter, the importance of X-ray diffraction (XRD) analysis for layered double hydroxide (LDH) polymer nanocomposites is presented and discussed. This chapter is basically divided into three main parts.

RESULT AND DISCUSSIONS According to the X-ray diffraction pattern as shown in figure 1, layered double hydroxide powder is well crystallized and exhibits sharp and symmetric peaks at low 2 θ...

2023年12月25日 · 层状双（金属）氢氧化物（Layered double hydroxides，简称LDHs），是一类具有二维纳米结构的层状材料，又称水滑石、类水滑石或阴离子粘土，主要由带正电的片层和层间阴离子组成。

聚合物／LDH纳米复合材料通常分插层型和剥离型2种结构形式。由于剥离型纳米复合材料中 LDH层板分散更均匀，已成为国内外学者研究的热点[48]。因LDH层板间静电作用力大，比蒙脱土更难 剥离。

2025年3月27日 · The XRD analysis of the CF, CF/Ni, CF/Co, and CF/CRBI-NiCo-LDH electrodes, reveals nearly identical diffraction patterns, all showing the same signals, which can therefore be assigned to the CF ...

2 天之前 · Characterization experiment method. The phase structure was tested by Shimadzu X-ray diffraction (XRD) (XRD-6100) using a target material of Cu K α1, λ = 0.15406 nm, X-ray tube voltage and current of 40 kV and 30 mA, respectively, and an angle of measurement in the range of 2θ = 2 ~ 70°. The morphology was observed by scanning electron microscopy (SEM) (JEOL-7600) and transmission electron ...

5 天之前 · From the XRD, the crystalline structures of pure g-C 3 N 4, CAL and a variety of g-C 3 N 4 /CoAl-LDH nanocomposites were studied. It is possible to assign the (100) and (002) planes of the g-C 3 N 4 to the two fundamental peaks of g-C 3 N 4 that are positioned at 13.2° and 27.6°, as shown in Fig. 1 (a) (PDF#50–1250).
