“…[25][26][27] The main reason is that MOF-derived CNMs could effectively maintain the structural features of MOF materials, such as high porosity, large specic surface area, high structural stability, and uniformly dispersed active sites. 27,[30][31][32] To date, researchers have been committed to improving their application performance from the initial selection of metal and ligands to the subsequent carbon synthesis. [28][29][30] First of all, metal cations are linked to ligand molecules in MOFs, and their coordination conguration determines the arrangement and positioning of ligands.…”

“…The stability of molecular electrocatalysts can be extended by sterically bulky ligand templates, yet along with the sacrifice of catalytic activity . Metal–organic frameworks (MOFs), composed of metal-ion/cluster nodes and organic linkers, represent a promising class of functional crystalline porous materials applied to various areas such as gas separation, sensing, catalysis, and drug delivery − due to their high specific surface area, tunable pores, rich topology, etc. − MOF is an ideal platform for a tailor-made heterogeneous catalyst as metal-centered active sites are well dispersed over the whole framework. Benefiting from the high surface area and porosity, additional active sites can be installed inside the framework through post-synthetic modification, PSM, to further enhance the catalytic activity of the MOFs.…”

A robust and porous Ni-based metal–organic framework (MOF), NiL1, was assembled from Ni(II) ions and a dipyrazolate linker (L1 2–). A Ni(II)-anchored MOF catalyst Ni@NiL1-Sal has been successfully prepared by post-synthetic modification (PSM) condensation between NiL1 with salicylaldehyde, followed by chelation of Ni(II) ions by salicylaldimine as a secondary active site. Ni@NiL1-Sal with carbon black was found to exhibit enhanced electrocatalytic hydrogen evolution reaction (HER) performance (the smallest overpotential, 384 mV, and Tafel slope, 87 mV dec–1) when compared with primitive NiL1 and NiL1-Sal. Such improvement in HER highlights the creation of unambiguous secondary active sites as an avenue to the rational design of a functional MOF-based electrocatalyst.

“…In this regard, the results of this study are significant because carboxylate-based drugs would be selectively targeted and removed in water by PCN–224 (Figure ). Our study provided an efficient methodology via the interaction between MOFs and other specific functional groups of organic pollutants. − …”

Chemically synthesized drugs used in the industry are associated with potential environmental risks. Herein, we report the targeted adsorption of nonsteroidal anti-inflammatory drugs, with and without a carboxylic acid group, using a water-stable Zr-based porphyrinic metal–organic framework (MOF), PCN–224. Nanoporous PCN–224 contains interaction sites for drugs and thus enables the removal of organic pollutants. The removal efficiency of NPX and IBP was 96 and 94%, but PCN–224 removed only 37% of SMX from water. The apparent difference in the adsorption efficiency of PCN–224 indicates that the carboxylic acid functional groups in drugs strongly interacted with the open metal sites of the PCN–224 Zr6 node via coordination bonding, resulting in a high adsorption capacity. This discovery provided a practical approach for the selective adsorptive removal of various other drugs with carboxylate groups.
