An unprecedented zeolite supramolecular framework featuring truncated cuboctahedral and truncated octahedral cavities was self-assembled from tetrahedral metal-organic cationic cages and tetrahedral anions. This crystalline porous material could trap iodine and organic dye molecules, and its solid state spin-crossover behavior was affected by guest encapsulation.

Hydrogen-bonded assembly of multiple components into well-defined icosahedral capsules akin to virus capsids has been elusive. In parallel, constructing robust zeolitic-like cluster-based supramolecular frameworks (CSFs) without any coordination covalent bonding linkages remains challenging. Herein, we report a cluster-based pseudoicosahedral H-bonded capsule Cu, which is buckled by the self-organization of judiciously designed constituent copper clusters and anions.

Pristine metal-organic frameworks (MOFs) are built through self-assembly of electron rich organic linkers and electron deficient metal nodes coordinate bond. Due to the unique properties of MOFs like highly tunable frameworks, huge specific surface areas, flexible chemical composition, flexible structures and a large volume of pores, they are being used to design the electrode materials for electrochemical energy storage devices. As per the literature, MOFs (including manganese, nickel, copper, and cobalt-based zeolitic imidazolate frameworks (ZIFs), University of Oslo (UiO) MOFs, Hong Kong University of Science and Technology (HKUST) MOFs and isoreticular MOFs (IRMOFs)) have attracted much attention in the field of supercapacitors (SCs)/batteries.

The therapeutic application of drugs often faces challenges due to non-specific distribution, inadequate dosification and degradation, which limits their efficacy. Two primary strategies are employed to overcome these issues: the use of derivatives of the active substances and incorporation of those into porous materials. The latter, involving materials such as zeolites, metal-organic frameworks (MOFs), and hydrogels, has shown promising results in protecting the active ingredients from degradation and enabling a controlled release.

The high efficient utilization of light absorption and the effective separation of photogenerated carriers are critical factors in enhancing the performance of photocatalysts. In this study, CoNi-layered double hydroxide was synthesized using zeolitic imidazolate frameworks-67 as a template, followed by calcination to form CoS/NiS. Subsequently, ReS was deposited onto the surface of CoS/NiS, resulting in the ReS/CoS/NiS photocatalyst demonstrated notable hydrogen evolution activity under visible light, achieving a maximum hydrogen production rate of 40111.

This study investigated the deactivation and regeneration of hierarchical zeolites in vacuum gas oil conversion, aiming to reach the equilibrium state seen in fluidized bed catalytic cracking (FCC). The research utilized various characterization techniques to analyze the properties of zeolites before and after coking and regeneration. Zeolite Y-0.
