Abstract Proton exchange membrane water electrolyzer (PEMWE) technology holds tremendous promise for large‐scale green hydrogen production. However, its widespread application faces significant constraints due to the limited lifespan of oxygen evolution reaction (OER) catalyst in highly acidic and oxidative operating environments. Therefore, a comprehensive understanding catalyst's structural degradation mechanism is imperative rational design high‐performance catalysts. In this review, essence catalysts: irreversible cationic anionic overoxidation initially unveiled. This followed by an in‐depth exploration their intricate relationship with adsorbate (AEM) lattice oxidation (LOM). Then, state‐of‐the‐art characterization techniques analysis are introduced. Subsequently, 4 cutting‐edge antioxidation strategies, including heterostructure engineering, doping strategy, nanostructuring, phase engineering systematically discussed, aiming reveal intrinsic factors effectively inhibiting overoxidation. Finally, remaining challenges prospective insights into catalysts PEMWE delineated. The overarching goal review facilitate fundamental mechanisms provide principal guidelines robust OER

Abstract Manipulating the electronic structure and coordination configuration of heterogeneous electrocatalyst is an advantageous strategy to motivate intrinsic activity but remains challenging. Herein, guided by theoretical mechanism d‐band center valence‐bond theory, high‐valence metal‐modulated nickel‐vanadium layered double hydroxides (M‐NiV LDH, M = Zr, Mo) with interfacial oxygen bridge bonding are rationally designed fabricated, affording a 3D vertically staggered porous nanosheets array network. Benefitting from abundant unfilled antibonding orbitals induced optimized Zr d‐orbital O p‐orbital hybridization, introduction site beneficial accelerate charge transfer kinetics optimize deprotonation OH* as well lower O* → OOH* free energy. As result, as‐prepared Zr‐NiV LDH exhibits promising evolution reaction performance low overpotential favorable long‐term stability. This work provides valuable insights into design electrocatalysts for regulation improvement.

Abstract Developing efficient, low‐cost electrocatalysts for industrial‐level hydrogen production remains a significant challenge. Here lattice‐distorted Ni nanoparticles (NPs) encapsulated within nitrogen‐doped carbon shell on delignified wood (Ni‐NC@DWC) are constructed through chitosan‐induced assembly and the pyrolysis process. Experimental theoretical results indicate that lattice distortion due to strong metal‐support interactions, boosts electron transfer reaction intermediate adsorption/desorption, enhancing both urea oxidation (UOR) evolution (HER). Interestingly, active center 3+ ‐O is dynamically cyclically generated during UOR. When utilized as self‐standing electrode in an alkaline electrolyte, Ni‐NC@DWC exhibits low potentials of 24 mV 1.244 V at 100 mA cm −2 HER UOR, respectively. Moreover, achieves ultrasmall cell voltage 1.13 urea‐assisted water splitting can operate stably over 1000 h. Furthermore, when it self‐assembled anion exchange membrane (AEM) electrolyzer, requires only 1.62 2000 industrial operates 150 h without degradation, confirming highly attractive economical, sustainable, scalable production.
