High-Entropy Metal-Organic Frameworks

Abstract

Highly stable high-entropy metal-organic frameworks (HEMOFs) are derived from polynuclear metal clusters, incorporating significant levels of all rare-earth metals without segregation. As an example, HEMOFs comprising nonanuclear metal clusters of rare-earth element ions with similar size and coordination chemistry connected by 1,2,4,5-tetrakis (4-carboxyphenyl) benzene linkers was developed, providing a metal-organic framework with high internal surface area and accessible Lewis acid sites. This new class of HEMOFs enables the development of multifunctional materials with tailored properties for a wide range of applications, including in catalysis. For example, these HEMOFs are highly active for CO2 fixation under mild conditions and short reaction times, outperforming existing heterogeneous catalysts.
