A porphyrin-based metal–organic framework with highly efficient adsorption and photocatalytic degradation performances for organic dyes

Abstract

Organic dye pollution has become an urgent issue due to their toxicity to humans and potential for damage to the environment. However, achieving highly efficient adsorption and degradation materials for...

Metal–organic framework-based materials: emerging high-efficiency catalysts for the heterogeneous photocatalytic degradation of pollutants in water

“…The improved photocatalytic performance of BiO–Ag(0)/C 3 N 4 @ZIF-67 is ascribed to the plasma effect of precious silver and increase in specific surface area. Chen et al 122 synthesized a porphyrin-based MOF photocatalyst with anionic groups. As a result of electrostatic interaction, the material had an effective adsorption effect on cationic dyes and the porphyrin-functional groups could guarantee the supply of singlet oxygen ( 1 O 2 ) and superoxide radicals (˙O 2 − ), and hence the dyes could be efficiently degraded.…”

Supramolecular squares of Sn(iv)porphyrins with Re(i)-corners for the fabrication of self-assembled nanostructures performing photocatalytic degradation of Eriochrome Black T dye

“…Hence, efficient treatments are required to eliminate this potentially toxic pollutant from wastewater. [45][46][47][48][49]…”

Highly stable Ni8-pyrazolate metal–organic frameworks for adsorption of methylene blue from water

“…Hence, it is imperative to eliminate MB from wastewater to prevent additional pollution of natural water bodies. Several methods have been developed to treat water pollution, such as photolysis, 5 electrolysis, 6 flocculation, 7 membrane filtration, 8 and adsorption. 9–11 In particular, the adsorption method has garnered significant attention in research due to its advantages of low cost, high efficiency, simplicity, and environmental sustainability.…”
