论文摘要
固体界面的反应在水处理系统，催化，化学分离以及预测环境中的化学命运和运输方面起着基础作用。在上个世纪，实验测量和计算模型在捕获固体表面的反应方面取得了巨大进步。但是，当固体表面局限于纳米级时，固体表面的界面反应性会发生巨大而出乎意料的变化。纳米芬可能会以不同的几何形状（例如毛孔/笼子（3-D限制），通道（2-D限制）和缝隙（1-D约束））产生。因此，根据这些测量值对无限制表面和分子模型进行了测量，无法捕获纳米填充下的化学行为。这篇综述评估了最新的实验和理论进步，重点是在固体界面上吸附。我们回顾了纳米结构如何改变水的物理化学特性，以及纳米结合水的结构和动力学如何决定纳米孔中吸附的能量，途径和产物。讨论了这些发现和未来研究方向的含义。
Reactions at solid-water interfaces play a foundational role in water treatment systems, catalysis, chemical separations, and in predicting chemical fate and transport in the environment. Over the last century, experimental measurements and computational models have made tremendous progress in capturing reactions at solid surfaces. The interfacial reactivity of a solid surface, however, can change dramatically and unexpectedly when it is confined to the nanoscale. Nanoconfinement can arise in different geometries such as pores/cages (3-D confinement), channels (2-D confinement) and slits (1-D confinement). Therefore, measurements on unconfined surfaces, and molecular models parameterized based on these measurements, fail to capture chemical behaviors under nanoconfinement. This review evaluates recent experimental and theoretical advances, with a focus on adsorption at solid-water interfaces. We review how nanoconfinement alters the physico-chemical properties of water, and how the structure and dynamics of nanoconfined water dictate energetics, pathways, and products of adsorption in nanopores. The implications of these findings and future research directions are discussed.
