Two-dimensional heterostructures built from ultrathin CeO₂ nanosheet surface-coordinated and confined metal-organic frameworks with enhanced stability and catalytic performance.

ABSTRACT: Two-dimensional (2D) metal-organic framework (MOF) based heterostructures will be greatly advantageous to enhance catalytic performance because they increase the contact surface and charge transfer. Herein, a novel 2D heterostructure named CeO₂@NiFe-MOFs, in which monolayer NiFe-MOFs is coordinated with ceria (CeO₂) to improve catalytic and stability performance, is successfully constructed by the strategy of in situ growth on the surface of ultrathin CeO₂ nanosheets being functionalized with monolayer carboxylic acid groups. The 2D heterostructure possesses a sandwich structure, where monolayer NiFe-MOFs are coordinated to both the top and bottom surface of CeO₂ nanosheets via joining carboxylic acid groups. In particular, CeO
