The surfactant-free bottom-up synthesis of ultrathin MOF nanosheets for the oxidation of isoeugenol to vanillin

Abstract

The direct synthesis of ultrathin MOF nanosheets is extremely challenging. Plenty of methods have been developed for the fabrication of MOF nanosheets, but these nanosheets suffer from structural deterioration, aggregation, morphological fragmentation, and low yields. Therefore, the direct synthesis of MOF nanosheets is more desirable, but this relies on our ability to easily and controllably synthesize them, which remains a challenging task. Herein, we report the direct bottom-up synthesis of MOF nanosheets comprising of assemblies of single layers, producing high crystallinity, surfactant-free low-cost MOF nanosheets with high yield.
