The scaling relationship among reaction intermediates with strongly correlated adsorption energy in the oxygen evolution (OER) severely restricts energy-conversion efficiency of water electrolysis. For conventional adsorbate mechanism, breaking remains challenging, as it is difficult to modulate multiple on a specific active site simultaneously. Herein, we utilize electron buffering effect two-dimensional fullerene network (C60NET) dynamically tune electronic structure iridium (Ir) change adsorbed intermediates, which can tailor strength from multistep reactions and break adsorption-energy relationships *OOH, *O, *OH. C60NET-buffered Ir nanocluster catalyst exhibits excellent OER activity low overpotential 237 mV stability over 600 h at 10 mA cm-2, outperforming graphene-supported nanoclusters commercial IrOx, attributed linear enabled by unique ability reversibly accept donate electrons C60NET.

Abstract The oxygen reduction reaction (ORR) is critical for energy conversion technologies like fuel cells and metal–air batteries. However, advancing efficient stable ORR catalysts remains a significant challenge. Iron‐based single‐atom (Fe SACs) have emerged as promising alternatives to precious metals. their catalytic performance stability remain constrained. Introducing second metal (M) construct Fe─M dual‐atom (Fe─M DACs) an effective strategy enhance the of Fe SACs. This review provides comprehensive overview recent advancements in Fe‐based DACs ORR. It begins by examining structural advantages from perspectives electronic structure pathways. Next, precise synthetic strategies are discussed, structure–performance relationships explored, highlighting role improving activity stability. also covers situ characterization techniques real‐time observation dynamics intermediates. Finally, future directions proposed, emphasizing integration advanced experimental with theoretical simulations well artificial intelligence/machine learning design highly active catalysts, aiming expand application storage technologies.

Abstract Seawater electrolysis is pivotal for sustainable hydrogen production, yet chloride‐induced catalyst corrosion severely hinders its efficiency. Here, a (Mo, Co)P x electrocatalyst via two‐step hydrothermal‐phosphorization strategy engineered, enabling in situ formation of dynamic dual‐anion (MoO 4 2 ⁻/PO 3 ⁻) Cl − ‐rejection interface. This tailored interface effectively blocks adsorption while preserving hydroxyl accessibility, significantly enhancing resistance alkaline seawater. The optimized delivers exceptional oxygen evolution reaction performance seawater electrolysis, achieving ultralow overpotentials 213 and 360 mV to reach current densities 10 1000 mA cm −2 , respectively. Remarkably, the with an situ‐generated rejection layer demonstrates durability, exhibiting only 20mV degradation during 480‐h stability test under high‐current conditions. In Raman spectroscopy, attenuated total reflectance surface‐enhanced infrared absorption density functional theory calculations demonstrate that not enhances but also promotes rapid surface reconstruction Co species interfacial water adsorption, thereby suppressing competitive chlorine reactions. work provides rational designing durable electrocatalysts situ‐engineered anion‐rejection interfaces, advancing efficient electrolysis.
