“…Cr-MIL-101 performed best with CO2 present. 162 Additionally, V-MIL-47 and Cr-MIL-53 were investigated for H2S capture at high pressures. Both V and Cr materials appear to be stable up to 15 bar H2S, whereas Fe-MIL-53 decomposes under similar conditions to what is likely iron sulfide and H2BDC.…”

Metal-organic frameworks (MOFs) have demonstrated their utility for a variety of applications involving the storage, separation, and sensing of weakly interacting gases of high purity. Exposure to more realistic, impure gas streams and interactions with corrosive and coordinating gases raises the question of chemical robustness, which remains a paramount concern for practical applications of MOFs. However, factors that determine the stability of MOFs remain incompletely understood. Although past researchers attempted to categorize framework materials as either thermodynamically stable or kinetically stable, recent work has elucidated an energetic penalty for porosity for all materials in this class with respect to a dense material. The metastability of porous phases has important implications for the design of materials for gas storage, heterogeneous catalysts, and electronic materials. Here, we focus on two main strategies for stabilization of the porous phase, either by using inert metal ions, or by increasing the heterolytic metal-ligand bond strength, both of which increase the activation barrier for framework collapse. These two strategies have led to exceptionally robust materials for the capture of coordinating and corrosive gases such as water vapor, ammonia, H2S, SO2, NOx, and even elemental halogens, and we review the progress in designing stable materials for these gases. Looking forward, we envision that the continued pursuit of strategies for kinetic stabilization in the synthesis of new MOFs will provide increasing numbers of robust frameworks suited to harsh conditions, and that short-term stability towards these challenging gases will be predictive of long-term stability for applications in less demanding environments.

Nanoparticles have become a vital part of a vast number of established processes and products; they are used as catalysts, in cosmetics, and even by the pharmaceutical industry. Despite this, however, the reliable and reproducible production of functional nanoparticles for specific applications remains a great challenge. In this respect, reticular chemistry provides methods for connecting molecular building blocks to nanoparticles whose chemical composition, structure, porosity, and functionality can be controlled and tuned with atomic precision. Thus, reticular chemistry allows for the translation of the green chemistry principle of atom economy to functional nanomaterials, giving rise to the multifunctional efficiency concept. This principle encourages the design of highly active nanomaterials by maximizing the number of integrated functional units while minimizing the number of inactive components. State-ofthe-art research on reticular nanoparticles-metal-organic frameworks, zeolitic imidazolate frameworks, and covalent organic frameworks-is critically assessed and the beneficial features and particular challenges that set reticular chemistry apart from other nanoparticle material classes are highlighted. Reviewing the power of reticular chemistry, it is suggested that the unique possibility to efficiently and straightforwardly synthesize multifunctional nanoparticles should guide the synthesis of customized nanoparticles in the future.

“…The hybridity and flexibility of MOFs gives them many desirable properties, such as high specific surface area, tunable pore size, and relatively good thermostability with exceptional chemical variety. [ 11 ] Hence, more and more researchers have applied MOFs to medicine delivery, [ 12,13 ] technology of gas storage and separation, [ 14–16 ] catalysis, [ 2 ] and sensing. [ 17–19 ] The combination of a wide range of metal ions and a variety of organic ligands enables the desired properties of MOFs to be conveniently tuned vis‐à‐vis a particular application.…”

A series of binary composite photo‐catalyst BiOBr/MgBTC (the ligand of MgBTC is 1, 3, 5‐benzenetricarboxylate = H3BTC) with different content of BiOBr have been designed and used to degrade the traditional dye rhodamine B (RhB). As‐prepared binary composites have been first obtained via a simple hydrothermal system and subsequently deposited onto the BiOBr substrates. The composites exhibited better catalytic performance compared with the pristine BiOBr, and the performance of BM‐55 (synthesized by 0.55 mmol BiOBr and 0.45 mmol MgCl2•6H2O) was the most efficient and its removal rate of RhB can reach 98.3% within 60 min. The composite photo catalyst was characterized by X‐ray diffraction (XRD), infrared (IR), scanning electron microscope (SEM), X‐ray photoelectron spectroscopy (XPS), diffuse reflectance spectroscopy (DRS), photoluminescence (PL), and electrochemical impedance spectroscopy (EIS), respectively. In the free radical trapping experiments, it can be seen that the main photo‐catalytic active species are superoxide radicals (•O2−) and holes (h+). This work can provide considerable opportunities to the development of various metal–organic frameworks (MOF)‐based visible light photo‐catalysts and modified 2D bismuth ox halide materials (BiOX) for use in environmental cleaning application.
