摘要

我们提出了一种基于配位化学的绿色合成路线，以制备纳米结构的层状双羟基化合物（LDHs）。合成的 NiAl-、NiFe- 和 ZnAl-LDHs 具有相似的形态和晶体结构。我们利用 pH 电位滴定法提出了 LDH 形成的可能机制。在配体场理论的透镜下对广泛的电子光谱进行解释分析，为了解 NiFe-LDH 的形成机理提供了关键信息。

Aqueous synthesis and electronic spectroscopy of layered hydroxide nanosheets

We propose a green synthetic route based on coordination chemistry to produce nanostructured layered double hy-droxides (LDHs). The synthesized NiAl-, NiFe- and ZnAl-LDHs present similar morphology and crystal structure. We pro-pose a possible mechanism of LDH formation by exploiting pH-potentiometric titrations. Extensive electronic spectrosco-py analyses, interpreted under the lens of ligand field theory, provides key insights into the formation mechanism of NiFe-LDH.
