“…When loading ketoprofen, all of the diffraction peaks are not shift, exhibiting no structural changes. However, some modifications in the intensities ratio of Bragg reflections can be seen probably due to some interatomic distances and bond angles was changed or the preferential orientation of crystallites imposed during drug loading process 16 , or due to the thin gelatinous film on the surface of Sr/PTA-MOF referring to the results of SEM 17 . Besides, characteristic peaks of ketoprofen were hard to find, which might be most of ketoprofen was encapsulated inside the MOF carrier or the low content.…”

A Sr-based metal-organic framework (MOF) is introduced as ketoprofen carrier to form a comprehensive system for treating osteoarthritis (OA), and the drug loading amount and release rate is investigated. Structural characterization of the samples showed that Sr/PTA-MOF had good crystal morphology and structure, and chemical and thermal stability. Ketoprofen was successfully loaded on the MOF carrier, which had been identified by high performance liquid chromatography (HPLC) and thermogravimetric analysis (TGA). The release experiment manifested that more than 90% of ketoprofen released from Sr/PTA-MOF after 24 h, and ketoprofen delivery was mainly governed by the Higuchi model. Furthermore, cytotoxicity experiment manifested that synthesized MOF carrier had no poisonous effect on OA chondrocytes, which provided a preliminary foundation for the realization of comprehensive treating OA.

“…A study investigated the change of hydrogen adsorption properties of HKUST‐1 with the increase of ball milling energy applied. The result exhibited that the decrease of hydrogen adsorption was in good correlation with the decrease of pore volume and surface area of HKUST‐1, which proved that porosity played an important role in hydrogen adsorption . However, in order to adsorb under mild conditions, the density of strong adsorption sites needs to be increased .…”

As a class of metal-organic frameworks (MOFs) formed by association of metal cations Cu 2+ with organic ligands benzene tricarboxylic acid, HKUST-1 [1] and its derivatives have attracted much concern as they possess highly porosity, ultrahigh surface area, and the tunable structure which show its potential in various applications. Unlike other porous materials like graphene (GN), [2] multiple layers of carbon nanotube (MCNT), [3] In recent decades, metal-organic frameworks (MOFs) have achieved rapid development owing to the considerable concern from researchers. As one of the most intensely studied MOFs, HKUST-1 has shown remarkable performance which is considered feasible to apply in actual applications. However, the weak mechanical properties and water instability hinder its development which are mainly ascribed to lattice defects and surface barriers that impede mass transfer and molecular diffusion as well as electronic transmission. This review summarizes the recent literatures on the strategies of enhancing the above defects of virgin HKUST-1 and its various applications, mainly adsorption and separation, catalyst, sensor as well as optical and electronic applications. These improving strategies improve specific properties of HKUST-1 by decreasing the defects density, which will make this material more applicable for potential fields. Main strategies include the following: (1) modifying HKUST-1 with an "armor," (2) getting durable MOFs by direct synthesis or surface hydrophobization, (3) reconstructing the moisture-degraded HKUST-1, and (4) making use of the buffer action of sacrificial bonds. . His current research focuses on metal-organic frameworks (MOFs), porous coordination polymers (PCPs), morph-genetic MOFs, biomimetic functional composite, nanomaterials, materials for energy and environment, photoelectric functional materials, and so on.

Usually, porous materials are synthesized by using conventional electric heating, which can be energy‐ and time‐consuming. Microwave heating is commonly used in many households to quickly heat food. Microwave ovens can also be used as powerful devices in the synthesis of various porous materials. The microwave‐assisted synthesis offers a simple, fast, efficient, and economic way to obtain many of the advanced nanomaterials. This review summarizes the recent achievements in the microwave‐assisted synthesis of diverse groups of nanoporous materials including silicas, carbons, metal–organic frameworks, and metal oxides. Microwave‐assisted methods afford highly porous materials with high specific surface areas (SSAs), e.g., activated carbons with SSA ≈3100 m2 g−1, metal–organic frameworks with SSA ≈4200 m2 g−1, covalent organic frameworks with SSA ≈2900 m2 g−1, and metal oxides with relatively small SSA ≈300 m2 g−1. These methods are also successfully implemented for the preparation of ordered mesoporous silicas and carbons as well as spherically shaped nanomaterials. Most of the nanoporous materials obtained under microwave irradiation show potential applications in gas adsorption, water treatment, catalysis, energy storage, and drug delivery, among others.
