Shape-selected colloidal MOF crystals for aqueous use

Abstract

Methods are described to synthesize shape-selectable, monodisperse, aqueous-stable metal-organic frameworks (MOFs) by the reaction of aluminium nitrate with benzene tricarboxylic acid in various aqueous solvent mixtures and acetic acid as the capping ligand. Environmental stability was confirmed by thermal analysis and immersion in aqueous acidic media.

Extra‐Framework Aluminum Species of Zeolite that Surrogate the Growth of Metal Organic Framework from Zeolite Matrix

“…The materialprepared with H 3 BTC and H-Betae xhibits XRD patterns corresponding to MIL-96 and H-BEA framework structures and the materiali sd esignated as H-Beta-Al-BTC-MOF ( Figure S12). [19] SEM image shows the octahedron like large crystal morphology for Al-BTC-MOF prepared in this study ( Figure S13). Such large micrometer size morphology is also seen to be grown from the H-Betam atrix when H-Beta is treated with H 3 BTC.…”

“…In this study, another framework such as Al‐BTC‐MOF is also grown using Al species present in the H‐Beta. The material prepared with H 3 BTC and H‐Beta exhibits XRD patterns corresponding to MIL‐96 and H‐BEA framework structures and the material is designated as H‐Beta‐Al‐BTC‐MOF (Figure S12) . SEM image shows the octahedron like large crystal morphology for Al‐BTC‐MOF prepared in this study (Figure S13).…”

Controllable Assembly of Al-MIL-100 via an Inducing Occupied Effect and Its Selective Adsorption Activity

“…[22][23][24] During the synthesis, it would be a dynamic process of precursor species for crystallization and recrystallization, which leads to the mixed phases. 25 For the purpose of verifying our proposed idea of inducing synthesis and eliminating the interference of other groups, homogeneous metal-containing AlPO 4 was prepared and used as inducing-agent in the above synthesis process.…”

Controlled synthesis of concave cuboctahedral nitrogen-rich metal–organic framework nanoparticles showing enhanced catalytic activation of epoxides with carbon dioxide

“…[45][46][47][48][49][50][51] The morphology manipulation of MOFs has also been reported recently, and some representative MOFs such as ZIF-8, HKUST-1, and MIL-96(Al) with specific shapes (for example, rod, cube, octahedron, and cuboctahedron) have been synthesized. [52][53][54][55][56][57][58][59][60][61] The MOF crystals with various shapes evidently exhibit different adsorbing properties. However, MOFs with a concave cuboctahedral structure have not been reported so far, probably due to insufficient theoretical study on the crystal growth mechanisms.…”
