Atomically detailed simulations have become an important complement to experimental studies of nanoporous materials. Large databases of crystalline porous material structures have been available for some years and these resources have significantly accelerated efforts to model diverse collections of these materials. Progress on simulating amorphous nanoporous materials, however, has been much slower, even though these materials have great importance in many applications. Previous studies on this topic have focused on one or at most a handful of model structures, in part, because creating these structures is intrinsically challenging. In this paper, we report a database of 205 atomically detailed models of amorphous nanoporous materials drawn from earlier literature, including carbons, polymers, kerogens, and other material classes. We computed a wide range of physical properties for each material, including multiple characteristics of the pores inside the material and simulations of single-component and binary gas adsorption. By making the structures of this diverse collection readily available, this database will help accelerate the use of atomically detailed simulations to explore a wide range of questions related to amorphous nanoporous materials.

多孔刚性非晶材料数据库

原子详细模拟已成为纳米多孔材料实验研究的重要补充。大型的晶体多孔材料结构数据库已经存在多年,这些资源极大地加快了对这些材料的各种集合进行建模的工作。然而,尽管无定形纳米多孔材料在许多应用中非常重要,但模拟它们的进展却慢得多。以前对此主题的研究仅关注一种或最多几种模型结构,部分原因是创建这些结构本质上具有挑战性。在本文中,我们报告了一个数据库,该数据库包含从早期文献中提取的205个无定形纳米多孔材料的原子详细模型,其中包括碳,聚合物,干酪根和其他材料类别。我们为每种材料计算了广泛的物理特性,包括材料内部孔隙的多种特性以及单组分和二元气体吸附的模拟。通过使该多样化集合的结构易于使用,该数据库将有助于加速使用原子详细的模拟来探索与无定形纳米多孔材料有关的广泛问题。
