Multi-metallic metal-organic frameworks and derived materials for electrochemical energy storage and conversion

There is much current research focused on advanced technologies for energy storage and conversion to mitigate environmental pollution and address concerns on future energy crises. Supercapacitors, batteries, and electrocatalytic water splitting are key technologies in this field with challenges on the development of efficient and durable electrode materials made of non-noble metals.۱ Metal−organic frameworks (MOFs) are particularly appealing materials because of remarkable structural diversity, tunable pore sizes and topologies, tailorable surface chemistry, and multiple functionalities. Engineering structural and electronic states of MOFs through decoration of functional entities is an effective way to advance the design of electrocatalysts and electrodes. Compared to mono- and bimetallic compounds, multimetallic MOFs often exhibit advantages in the context of new energy technologies, namely an enhanced electrochemical activity and electronic conductivity, higher number and diversity of active sites, superior charge capacity and transfer.۲ In this review, recent developments on heterotrimetallic MOFs and derivatives as extraordinary materials for applications in electrocatalytic water splitting, batteries, supercapacitors, and other environmentally significant uses are summarized. This work extends prior reviews on mono- and bimetallic-MOF based systems with a main goal of creating a roadmap for introducing heterotrimetallic MOFs as future generation materials for electrochemical energy storage and conversion
