Functionalized Thorium-Based Metal-Organic Frameworks for the Photocatalytic Oxidation of 1, 5-Dihydroxynaphthalene.

It is still a challenging task to rationally design metal-organic framework (MOF) crystal catalysts with excellent light absorption and charge transfer for efficient photocatalytic reactions. In this work, the hexanuclear thorium clusters, porphyrin derivative ligands, and linear carboxylic acid ligands were assemed into Th-based metal-organic frameworks (Th-TCPP, Th-Co-TCPP, and Th-Ni-TCPP) by the mixed ligand method. The three prepared MOF crystals were applied in the photocatalytic oxidation of 1, 5-dihydroxynaphthalene (1, 5-DHN) for the synthesis of juglone.

When microplastics/plastics meet metal-organic frameworks: turning threats into opportunities.

Significant efforts have been devoted to removal and recycling of microplastics (MPs; <5 mm) to address the environmental crises caused by their ubiquitous presence and improper treatment. Metal-organic frameworks (MOFs) demonstrate compatibility with MPs/plastics through adsorption, degradation, or assembly with the MPs/plastic polymers. Above 90% of MPs/plastic particles can be adsorbed on MOF materials the hydrophobic interaction, electrical attraction, π-π stacking, and van der Waals forces.
