About

Hydrogen production via water electrolysis, particularly anion exchange membrane water electrolyzer (AEMWE), is gaining growing prominence for renewable energy storage, yet its large-scale commercialization is impeded by limited membrane stability, slow electrochemical reaction kinetics, and unreliable long-term performance, with the anodic oxygen evolution reaction (OER) being the dominant kinetic bottleneck. To tackle this challenge, intensive research has focused on non-noble metal electrocatalysts, and layered double hydroxides (LDHs) with tunable bimetallic/ternary metal compositions stand out as promising candidates. Rational regulation of metal ratios and synergistic metal sites in LDHs (e.g., Ni-Fe, Ni-Cr) optimizes electronic structure and OER intermediate adsorption, remarkably enhancing catalytic performance and durability to advance the practical application of AEMWEs.
