The past decade has seen significant progress in proton exchange membrane water electrolyzers (PEMWE), but the growing demand for cost-effective electrolytic hydrogen pushes higher efficiency at lower costs. As a complex system, performance of PEMWE is governed by combination multiscale factors. This review summarizes latest from quantum to macroscopic scales. At level, electron spin configurations can be optimized enhance catalytic activity. nano and meso scales, advancements atomic structure optimization, crystal phase engineering, heterostructure design improve mass transport. macro scale, innovative techniques gas bubble management internal resistance reduction drive further gains under ampere-level operating conditions. These modifications level cascade through meso- macro-scales, affecting charge transfer, reaction kinetics, evolution management. Unlike conventional approaches that focus solely on one scale-either catalyst (e.g., atomic, or modifications) device porous transport layers design)-combining optimizations unlocks greater improvements. Finally, perspective future opportunities engineering anode toward commercial viability offered.

Phase transition engineering of metal–organic frameworks (MOFs) presents a promising strategy for enhancing electrocatalytic performance in water splitting applications. In this study, we demonstrate controlled phase to synthesize multiphase composite (op&cp) composed open (op) and closed (cp) through precise desolvation treatment. When used as an alkaline electrocatalyst, op&cp exhibits exceptional oxygen evolution reaction (OER) performance, achieving remarkably low overpotential 140 mV under 10 mA cm–2 maintaining stable operation over 75 h at 100 cm–2. situ Raman spectroscopy X-ray photoelectron show that the catalytically active substance NiOOH is formed on engineered with lower potential (1.2 V vs RHE) than single-phase material (1.3 RHE). This work establishes viable improving MOF-based catalysis explores fundamental mechanism dynamic sites during OER.

Abstract In water electrolysis, the long‐term stability of anodes is compromised by their degradation under oxidative conditions. This issue becomes more pronounced in seawater where natural chloride ion (Cl − ) induces chlorine evolution reaction (ClER) to produce corrosive byproducts. Herein, a series small organic molecules (SOMs), featuring an aromatic carbon ring with para‐positioned carbonyl groups, are integrated conventional nickel‐iron (Ni‐Fe) based anode. integration triggers unique electron buffering effect address anode seawater‐based electrolytes. It found that preferential adsorption Cl onto SOMs prevents its direct interaction metal active sites. Furthermore, SOM‐Cl serving as group significantly reduces dissolution Fe sites highly environment. As result, SOM‐Cl‐engineered enhances oxygen activity ≈1.7 times compared pure water. addition, rationally designed works stably for over 200 h at high current density 1.3 A cm −2 alkaline electrolyzer (ASE).
