Metal-organic framework nanoshell structures: Preparation and biomedical applications

Defect-engineered Zr-MOFs with enhanced O2 adsorption and activation for photocatalytic H2O2 synthesis

“…Metal–organic frameworks (MOFs) are multifunctional materials constructed by coordination bonds between inorganic nodes (metal ions/metal clusters) and organic ligands, 10,11 which have a broad range of applications. 12–14 Particularly, due to their semiconducting behavior and tunable optical properties, MOFs are in the spotlight in photocatalysis. 15–17 Nonetheless, photocatalytic performances of pristine MOFs are usually poor owing to the rapid recombination of photo-induced charge carriers.…”

pH-responsive on-demand release of eugenol from metal–organic frameworks for synergistic bacterial killing

“…10 A growing number of studies have focused on the application of MOFs in fluorescent detection, gas storage, chemical catalysis, bio-sensing, drug delivery, and antibacterial activity. 11–14 MOFs have been shown to act as antibacterial agents with different mechanisms. First, MOFs can continuously release metal ions and organic ligands to afford certain antibacterial activity owing to the reversibility of their coordination bonds.…”

Temperature-Controlled Synthesis of Trimodal Hierarchically Porous MOFs with Variable Core–Shell Configurations

“…Besides the construction of meso- or macropores, the design of MOFs with hollow voids has also attracted enormous interests. Benefiting from the inherent porous skeletons of MOFs, porous shells provide faster diffusion paths for guest molecules to enter into internal cavities, which makes hollow MOFs more competitive than traditional hollow SiO 2 or carbon-based materials in storage, biomedical, catalysis, and energy-related applications. − Among various strategies for the formation of hollow cages, etching is a classic top-down method to create voids inside MOFs based on the stability difference between the templates or intermediate products and MOF shells. − However, for homogeneous and compact MOFs, the etching generally results in randomly distributed voids or even the destruction of whole structures. , Moreover, in most cases of hollow MOFs, the shell is still limited to microporous structure, and there are few, if any, reports about hollow MOFs with mesopores in the highly crystallized shells. , …”
