2022年3月15日 · Novel CoBiTi LDH (CBT-LDH) were prepared and easily oxidized at 150 °C to CBTO. A novel heterojunction by CBT-LDH and CBTO was successfully prepared. A novel strategy to boost solar-induced hydrogen generation is introduced. High HE-rate by ∼5 folds could be achieved by a narrow bandgap without scavengers.

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。

层状双金属氢氧化物（Layered Double Hydroxide,LDH）是水滑石（Hydrotalcite,HT）和类水滑石化合物（Hydrotalcite-Like Compounds,HTLCs）的统称，由这些化合物插层组装的一系列超分子材料称为水滑石类插层材料（LDHs）。

2022年10月14日 · Layered double oxides (LDOs) can restore the parent layered double hydroxides (LDHs) structure under hydrous conditions, and this “memory effect” plays a critical role in the applications...

2024年4月15日 · In this work, we report the strategy of the LDH→LDO intermediate-transformation amorphization to improve the performance of the LDH anode material. Firstly, flower-like NiCo-LDH nanoparticles were synthesized using triethanolamine (TEA) as a morphology modifier and gentler precipitant, and hydrogen peroxide (H …

基于 LDHs 材料特有的记忆效应，本工作围绕 MgFe-LDH 的制备及焙烧改性的策略，合成了相应的层状双金属氧化物 （LDOs） ，实现了对铅离子的高容量矿化，饱和矿化容量为2406 mg/g 。除此之外，该材料也具有良好的抗酸性与离子选择性。

2022年1月1日 · Ultra-thin BMIMPF6 and N, N-dimethylformamide modified LDH (LDH-Me) and calcined production LDO-Me nanosheet materials were used to remove trace phosphate from water. Due to the memory effect, the removal by LDO-Me (94.10 %) was significantly higher than that of LDH-Me (87.90 %), and the adsorption capacity was surprisingly higher than that of ...

研究显示，Mg/Al-LDH和Mg/Al-LDO可实现含磷水样的高效快速去除，从而为今后市政污水处理技术的革新提供新 思路. 关键词： 层状双金属氢氧化物(LDH)；LDO；磷酸盐；吸附；去除

2025年1月3日 · Different methods for rehydrating MgAl layered double hydroxides (LDHs) were tested in combination with zeolite. The optimal rehydration of MgAl/LDHs was achieved at 300 °C in an inert atmosphere under a flow of He gas.

The increasing threat of chloride ions (Cl−) has led researchers to explore efficient removal technologies. Sewage treatment with a double-layer hydroxide/oxide (LDH/LDO) is receiving increasing attention. In this work, Mg-Al LDO adsorbents were ...
