Recent Advances in MOF-Derived PGM-Free ORR Catalysts: From Active-Site Engineering to Working Cathodes
The oxygen reduction reaction (ORR) remains a major bottleneck in terms of kinetics and durability in fuel cells and zinc–air batteries (ZABs). Metal–organic frameworks (MOFs) are versatile precursors for platinum-group metal (PGM)-free ORR electrocatalysts because their metal distribution, ligand chemistry, guest conf...
