The discovery of acid-stable and highly active electrocatalysts for the oxygen evolution reaction (OER) is crucial in quest high-performance water-splitting technologies. Herein, a heterostructured RuO2–CeO2 electrocatalyst was constructed by using lattice-matching strategy. interfacial Ru–O–Ce bridge structure provided channel electron transfer between Ru Ce, creating lattice stress that distorts local RuO2. resulting catalyst exhibited attractive stability with negligible decay after 1000 h OER 0.5 M H2SO4, along high activity an overpotential only 180 mV at 10 mA cm–2. In situ attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS), differential electrochemical mass spectrometry (DEMS), density functional theory (DFT) calculations were used to reveal interface noninterface RuO2 sites enabled oxide path mechanism (OPM) enhanced adsorbate (AEM-plus), respectively, during OER. simultaneous independent pathways accessible matching guides improved design acidic media.

The active-site density, intrinsic activity, and durability of Pd-based materials for oxygen reduction reaction (ORR) are critical to their application in industrial energy devices. This work constructs a series carbon-based rare-earth (RE) oxides (Gd2 O3 , Sm2 Eu2 CeO2 ) by using RE metal-organic frameworks tune the ORR performance Pd sites through Pd-REx Oy interface interaction. Taking Pd-Gd2 /C as representative, it is identified that strong coupling between Gd2 induces formation Pd-O-Gd bridge, which triggers charge redistribution . screened exhibits impressive with high onset potential (0.986 VRHE ), half-wave (0.877 excellent stability. Similar results also found Pd-Sm2 /C, Pd-Eu2 Pd-CeO2 catalysts. Theoretical analyses reveal promotes electron transfer antibonding-orbital occupancy Pd-*OH optimization *OH adsorption rate-determining step ORR. pH-dependent microkinetic modeling shows close theoretical optimal activity ORR, outperforming Pt under same conditions. By its ascendancy superior Zn-air battery an air cathode, implying practicability.

Abstract Single‐atom catalysts (SACs) are demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs still early stages of conversion, problems like agglomeration low conversion efficiency hampering their practical applications. Substantial research focus on support modifications, which vital SAC stability due intimate relationship between atoms support. In this review, category supports variety surface engineering strategies employed SA systems summarized, including site (heteroatom doping, vacancy introducing, groups grafting, coordination tunning) structure (size/morphology control, cocatalyst deposition, facet engineering, crystallinity control). Also, merits single‐atom systematically introduced. Highlights comprehensive summary discussions utilization surface‐engineered diversified applications photocatalysis, electrocatalysis, thermocatalysis, devices. At end potential obstacles using field discussed. This review aims guide rational design manipulation target‐specific capitalizing characteristic benefits engineering.
