Abstract:Layered double hydroxides (LDH) are successful candidates for electrocatalytic oxygen evolution reaction (OER). Unfortunately, their catalytic kinetics and long-term stability are far unsatisfactory comparing to rare metals in practice. Here we track the endurance of NiFe-LDH and uncover that the ablation of lamellar structure caused by metal dissolution is the immediate reason for the decreased stability. Inspired by amino acid residues in photosystem II, we report a strategy using trimesic acid anchor to ach… Show more
