Stability Regulation of Metal-organic Framework Materials for Electrocatalysis

Abstract

The stability of metal-organic framework materials (MOFs) greatly affects their catalytic performance and cycle life in practical applications. However, while the number and diversity of MOF structures have increased significantly in recent years, the stability of MOFs has not been sufficiently investigated, and even less literature has been written to deeply analyze the reasons for the stability of the material from the framework structure of MOFs. Considering the importance of the structure-activity relationship, this review analyzes and discusses the thermodynamic and kinetic factors affecting the structural stability of MOF and sums up the connection between MOF stability and catalytic activity. The regulation strategies and representative cases of MOF stability are summarized. Finally, the expectations of machine learning and construction defects are put forward for the future development direction of MOF. Based on the contents of the above review, a deep understanding of the factors destabilizing the MOF framework and the existing strategies for stability regulation will help a wide range of researchers to develop highly structurally stable and high-performance stabilized MOF catalytic materials and make new breakthroughs in the field of electrocatalysis.
