黏土矿物广泛分布于自然界中,其对地质和地球化学过程有重要意义,也是工业、环境等领域中的重要矿物材料。黏土矿物的众多物化性质均与其表界面结构和性质有关。作为实验研究方法的重要补充,量子力学模拟被广泛用于黏土表界面性质的研究。本文回顾了利用量子分子动力学模拟对黏土矿物-水界面性质的研究,包括表界面结构、表面酸度和离子络合等方面。
Clay minerals are ubiquitously distributed in nature and play important roles in many geological and geochemical processes. They are also important materials in environmental and industrial fields. As a useful complement to experiments,quantum molecular dynamics has been widely applied to studies of interfaces of clay minerals. This paper reviews the works of FPMD( first principle molecular dynamics) simulations on clay mineral-water interfaces,including interface structure,surface acidity and ion complexation.
