Applications of high-entropy MOFs and their derivatives

Abstract

The compositional and structural tunability of high-entropy metal-organic frameworks (HE-MOFs) and their derivatives has pivotal impact on photocatalytic, electrocatalytic, and thermocatalytic performances. Here, we systematically summarize the synthesis methods of HE-MOFs and their derivatives. Then, regulation strategies to improve the catalytic performances are outlined, including pore regulation, morphology regulation, defect engineering, element regulation and interface engineering. Meanwhile, the electro−/thermo−/photo-chemical applications of the recently emerged HE-MOFs and their derivatives for various catalytic processes, such as oxygen reduction/evolution reaction (ORR/OER), hydrogen evolution reaction (HER), nitrogen reduction reaction (NRR), alcohol oxidation reaction, hydrogenation reaction, and cycloaddition reaction, are outlined. Finally, the pivotal challenges and perspectives of HE-MOFs and their derivatives for related applications are highlighted.
