Abstract

Water stability is one of the most important factors restricting the practical application of metal organic frameworks (MOFs). In this work, we fabricate a highly defective HKUST-1 framework with a mixed valence of CuI/CuII by mechanical ball milling method. This defective HKUST-1 is embellished by functionalized ionic liquids as hydrophobic armor, making the hybrid HIL1@HKUST-1 exhibits outstanding water stability, remarkable SO2 adsorption (up to 5.71 mmol·g−1), and record-breaking selectivity (1070 for SO2/CO2 and 31515 for SO2/N2) at 25oC and 0.1 bar, even in wet conditions.

高度缺陷的HKUST-1具有优异的稳定性和SO2吸收量:功能化离子液体的疏水装甲效应

水稳定性是制约金属有机骨架(MOFs)实际应用的重要因素之一。在这项工作中，我们用机械球磨法制作了一个具有高缺陷的CuI/CuII混合价态的HKUST-1框架。这个缺陷的HKUST-1被官能化离子液体修饰为疏水盔甲，使得杂化物HIL1@HKUST-1在25℃和0.1 bar条件下，即使在潮湿条件下，也表现出出色的水稳定性，出色的SO2吸附(高达5.71 mmol·g−1)和破纪录的选择性(对SO2/CO2的选择性为1070，对SO2/N2的选择性为31515)。

期刊介绍： Green Energy & Environment (GEE) is an internationally recognized journal that undergoes a rigorous peer-review process. It focuses on interdisciplinary research related to green energy and the environment, covering a wide range of topics including biofuel and bioenergy, energy storage and networks, catalysis for sustainable processes, and materials for energy and the environment. GEE has a broad scope and encourages the submission of original and innovative research in both fundamental and engineering fields. Additionally, GEE serves as a platform for discussions, summaries, reviews, and previews of the impact of green energy on the eco-environment.
