Functional Nanomaterials MOF-based Electrocatalysts for ORR OER and HER, Recent Development Challenges and Future Perspectives

Abstract

In recent years, metal-organic framework (MOF)-derived single-atom catalyst (SAC) nanomaterials have emerged as promising fuel cell and battery electrocatalysts. This article explores the advancements in the synthesis and characterization of MOF-derived SAC nanomaterials and their applications in energy storage and conversion devices. The unique properties of single-atom catalysts will be discussed, including their high activity, selectivity, and stability, which make them highly desirable for electrocatalytic reactions. Different strategies to prepare MOF-derived SAC nanomaterials will also be elaborated, such as thermal activation, etching, and atom trapping. We also highlight the key electrochemical reactions, such as oxygen reduction reaction (ORR), hydrogen evolution reaction (HER), and oxygen evolution reaction (OER), where MOF-derived SACs have shown remarkable performance. Moreover, we present a comprehensive overview of the recent advancements in the utilization of MOF-derived SAC nanomaterials, highlighting their potential to revolutionize energy storage and conversion technologies. Finally, we address the current challenges and future perspectives in this field, emphasizing the need for further research to enhance the scalability and commercial viability of MOF-derived SACs. Overall, this review article provides valuable insights into the development and potential applications of MOF-derived SAC nanomaterials for fuel cells and batteries, paving the way for sustainable and efficient energy systems.
