Non‐Noble Metal Ion‐Based Metal‐Organic Framework Electrocatalyst for Electrochemical Hydrogen Generation

With global energy demand predicted to skyrocket in the next few decades, the creation of a sustainable energy system to meet this demand is critical. We must store the energy produced by renewable sources in some resilient form, because of constraints with their utilization, such as lack of sunlight, low wind speed, and so on. Hydrogen is an excellent choice for this task. Water splitting to fabricate and process sustainable hydrogen is an enticing approach for hydrogen energy to attain a carbon-free future. However, efficient electrocatalysts are required to enhance cathodic hydrogen evolution and anodic oxygen evolution for this technology to be realized and scaled up. This chapter focuses on the basic concept related to metal–organic frameworks (MOFs) and also highlights their benefits as electrocatalysts over those traditionally used. Further, special emphasis is paid to design principles, fabrication, methodologies, and structure–property interactions. Enhancement of catalytic efficiency by introducing heteroatoms, making composites with carbon materials, and synthesizing nanomaterials, are discussed.
