Research Progress on the structure of hydration films at solid-liquid interface

  • 摘要: 固液界面水化膜是化学反应的主要场所,在矿物学、表面科学和环境科学等领域具有重要作用,水化膜结构的研究能够为上述领域的发展提供依托。本文以云母、方解石和石墨三种常见矿物为例,总结了利用X射线反射率(XR)和原子力显微镜(AFM)两种方法探索矿物-水界面水化膜结构的研究进展,探讨了不同矿物表面水化膜的结构特点,讨论了溶液中金属阳离子、矿物表面解离离子及附着物对水化膜结构的影响,对比了两种方法所测水化膜结构的异同点。本文旨在深化对固液界面水合结构的理解,推动水化膜动力学行为的深入研究。

     

    Abstract: The solid-liquid interface is the primary site for chemical reaction, which is critical in the research field of mineralogy, surface science and environmental science. The research on structure of hydration films could support the development for those areas. This review takes mica, calcite and graphite as examples and summarizes the research progresses on the structure of hydration films at solid-liquid interface explored by X-ray reflectivity (XR) and Atomic Force Microscopy (AFM). The structures of hydration films on different mineral surfaces are discussed. Besides, the influences of metal cations in solution, dissociation ions on mineral surface as well as the contaminations on mineral surface on the structure of hydration films are reviewed. The structures of hydration films obtained by XR and AFM are compares as well. The objective of this review is to deepen the understanding of the hydration structure at the solid-liquid interface and promote in-depth research on the dynamic behavior of hydrated films.
