Polyoxometalates for Oxygen Evolution Electrocatalysis: From Molecular Active Motifs to Interfacial Regulators and Practical Electrolyzers
The oxygen evolution reaction (OER) remains the principal kinetic bottleneck in water electrolysis because its multistep proton-electron transfer is coupled with dynamic structural evolution under anodic bias. Beyond the intrinsic four-electron barrier, practical operation is constrained by metal dissolution, phase...
