Abstract:	摘要： The creation of hierarchical porosity in metal-organic frameworks (MOFs) could benefit various applications of MOFs such as gas storage and separation. Having single-crystalline microcrystals instead of poly-crystalline composites is critical for these potential applications of MOFs with hierarchical porosity. We developed a room temperature synthetic method to generate uniform hollow and mesoporous zeolitic imidazolate framework-8 (ZIF-8) microcrystals with a single-crystalline structure via overgrowing a ZIF-8 shell in methanol solution on a ZIF-8 core with water adsorbed in the pores. The cavities formed as a result of the different solvent micro-environment. This double-solvent mediated overgrowth method could be applied to prepare other MOFs with hierarchical porosity. A double-solvent mediated overgrowth method is developed to form cavities in single-crystalline MOF microcrystals. Due to the different solvent effects, hollow structures are created. 出版日期： 2015-11-19 識別號： ISSN: 2040-3364 識別號： EISSN: 2040-3372 識別號： DOI: 10.1039/c5nr06532a
