Metal–Organic Framework-derived Bifunctional Electrocatalysts

This chapter provides an introduction to the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) and discusses the fundamental aspects and their significance in different applications. Measurements of different electrochemical parameters needed for the measurement of the OER and ORR performance of a catalyst are considered. A novel class of advanced porous hybrid materials has emerged: metal–organic frameworks (MOFs) with variable pore sizes and large surface areas characterized by various periodic patterns. Because of their immense porosity and mechanical and thermal durability, they are used in a wide variety of applications. However, the low electrical conductivity and poor stability of MOFs make their use in electrocatalysis difficult. The benefits of using MOF-derived materials as bifunctional electrocatalysts for OER and ORR are discussed.
