Abstract:

This article reviews the recent progress on predicting the adsorption properties of metal-organic framework by using classical density functional theory and focused on the application of the classical density functional theory to the high-throughput screening, which is accelerated by Fast Fourier Transform. Comparing to the conventional molecular simulations, the advantage of the accelerated classical density functional theory is the calculation speed, especially for simple small molecule systems, which makes the high-throughput screening on MOF materials feasible. However, it appears that there is a lack of efficient method to deal with the complicated molecules. How to construct a reasonable free energy functional of complicated fluid is the main challenge to state of art classical density functional theory.

Key words: metal-organic framework, classical density functional theory, adsorption, statistical thermodynamics, gas

摘要:

回顾了近年来经典密度泛函理论在预测金属-有机骨架材料吸附特性方面的研究进展,重点介绍了经过快速傅里叶变换加速后的经典密度泛函理论在MOF吸附材料的大规模筛选方面的应用。相较传统的计算机分子模拟,加速后的经典密度泛函理论的优势在于计算效率,对于简单的小分子气体系统尤其具有优势,对MOF吸附材料进行大规模筛选是可行的;但对于对复杂分子的处理尚没有特别有效的方法,如何合理构建复杂流体自由能泛函是它面临的主要挑战。
