摘要

为了寻求高效节能、对环境无害的 C4 碳氢化合物混合物分离方法,人们开始探索多孔材料,其中沸石和金属有机框架(MOFs),尤其是 MOFs 走在了前列。这些材料具有可调节的孔隙大小、多种化学功能以及在外部刺激下发生结构转变的能力,这些特性都是分离过程非常需要的。本综述深入分析了 C4 碳氢化合物吸附分离的基本原理,包括热力学、动力学、分子筛分、响应框架分离和客体构象控制机制。报告还探讨了提高多孔材料选择性和稳定性的策略,如引入开放金属位点、官能团修饰和柔性框架工程。讨论还延伸到当前这些材料在工业应用中的局限性和挑战。本综述总结了最近的突破并确定了关键的研究方向,旨在为未来的研究工作提供战略路线图。

Zeolite and metal-organic framework based microporous crystalline materials in adsorption separation of C4 hydrocarbons
The quest for energy-efficient and environmentally benign methods for separating C4 hydrocarbon mixtures has led to the exploration of porous materials, with zeolites and metal-organic frameworks (MOFs), especially MOFs at the forefront. These materials exhibit tunable pore sizes, diverse chemical functionalities, and the capacity for structural transformation in response to external stimuli, attributes that are highly desirable for separation processes. This review provides an in-depth analysis of the fundamental principles governing the adsorptive separation of C4 hydrocarbons, including thermodynamic, kinetic, molecular sieving, responsive framework separation, and guest conformation-controlled mechanisms. It also examines strategies to enhance the selectivity and stability of porous materials, such as the introduction of open metal sites, functional group modifications, and the engineering of flexible frameworks. The discussion extends to the current limitations and challenges in the industrial application of these materials. By synthesizing recent breakthroughs and identifying pivotal research directions, this review aims to offer a strategic roadmap for future research endeavors.

期刊介绍: Coordination Chemistry Reviews offers rapid publication of review articles on current and significant topics in coordination chemistry, encompassing organometallic, supramolecular, theoretical, and bioinorganic chemistry. It also covers catalysis, materials chemistry, and metal-organic frameworks from a coordination chemistry perspective. Reviews summarize recent developments or discuss specific techniques, welcoming contributions from both established and emerging researchers. The journal releases special issues on timely subjects, including those featuring contributions from specific regions or conferences. Occasional full-length book articles are also featured. Additionally, special volumes cover annual reviews of main group chemistry, transition metal group chemistry, and organometallic chemistry. These comprehensive reviews are vital resources for those engaged in coordination chemistry, further establishing Coordination Chemistry Reviews as a hub for insightful surveys in inorganic and physical inorganic chemistry.
