2025年1月27日 · Layered double hydroxides (LDH) containing various exchangeable anions were studied to show how X-ray Photoelectron Spectroscopy (XPS) can provide information on the local environments of the different elements within the interlayer anionic groups and their possible influence on the LDH interlayer hydroxide surfaces.

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。LDHs的结构如下图所示，其化学通式表示为：[M1-x2+Mx3+(OH)2]x+Ax/nn-·zH2O，其中，M2+为 ...

2025年2月1日 · LDHNSs exhibited ultra-high sorption capacity of 1502 mg/g for PFOS, which represents an 82 % increase compared to conventional LDHs. Multi-mechanisms (ion exchange, electrostatic interaction, oxygen vacancies) lead to high removal efficiency of PFOS. LDHNSs poses stable performance across various matrices with robust reusability.

2022年6月1日 · Hexagonal Zn–Al hydrotalcite (Zn–Al LDHs) has become a research hotspot in the field of photocatalysis due to efficient photocatalytic performance, low cost and non-toxicity. In this research, In2 S 3/Zn–Al LDHs composites were firstly synthesized by one-pot method with InCl3 and TAA as raw materials.

2024年1月1日 · Layered double hydroxides (LDHs) are a class of two-dimensional anionic clays with adjustable structure, which have certain corrosion resistance. However, smooth growth path of LDHs nanosheets perpendicular to the substrate limits its application in the field of corrosion.

Nickel aluminum layered double hydroxide (NiAl LDH) with nitrate in its interlayer is investigated as a negative electrode material for lithium-ion batteries (LIBs). The effect of the potential...

2019年7月24日 · Herein, we report a one-step hydrothermal method to facilely fabricate vertically aligned NiFe LDH nanosheet arrays on free-standing nitrogen doped graphite foams (NGF) under an appropriate amount of urea as a hybrid OER electrode (NiFe LDH/NGF).

Antioxidants intercalated Mg/Al LDH was synthesized and successfully characterized by PXRD, FTIR, XPS, Raman, SEM, and EDS. The shifts in the LDHs’ peaks in PXRD indicated the successful...

Layered double hydroxides (LDHs) have recently attracted much attention in the scientific community as a prominent catalyst for oxygen evolution reaction (OER) because they are economical,...

在本报告中，我们提出了一种使用Rietveld精制，XPS和XANES表征LDH晶体结构的分析方法。 使用这种分析方法，我们发现通过一种新的简便合成路线制备的ZnCo LDH纳米板具有Zn 3.1 Co 1.9 Cl 2（OH）8 ·H 2与先前报道的ZnCo LDH不同，O结构具有很大一部分二价Co阳离子。
