Considering 21 candidate elements at a 1% atomic resolution, this combinatorial explosion exceeds 10 billion (&gt;10¹⁰) possibilities, rendering direct experimental exploration impractical. Furthermore, purely data-driven approaches often struggle to comprehend the intrinsic chemical roles of discrete elemental identities, yet they excel at mapping continuous concentration gradients. Recognizing this distinction, we transform this combinatorial explosion into a targeted optimization problem by decoupling elemental selection from compositional ratio refinement. Ultrafast carbon thermal shock (CTS) is first employed to screen viable elemental combinations and establish an optimal quinary framework. Machine learning (ML) is subsequently applied to optimize compositional ratios within this reduced space, where statistical modeling efficiently navigates the remaining high-dimensional landscape. Targeting the oxygen evolution reaction (OER) as a proof-of-concept, our hybrid framework pruned the search space from over 10¹⁰ possible compositions down into 13 systems, ultimately identifying high-entropy oxide (HEO)-Fe_17.57Co_28.45Ni_31.27Mo_10.57Zr_12.14 as the optimal catalyst. The optimized high-entropy oxide exhibits an overpotential of 240 mV at 10 mA cm⁻² and sustains stable operation at 1 A cm⁻² for over 600 h in 1 M KOH. Mechanistic analysis reveals that Mo electronically tunes oxygen-intermediate adsorption, while Zr enhances structural robustness, collectively enabling high activity and durability. This work demonstrates that bridging discrete physical screening with continuous data-driven optimization provides an efficient and generalizable pathway for navigating high-dimensional material frontiers.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"69 10","pages":"6112 - 6120"},"PeriodicalIF":7.7,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149099223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its efficiency is limited by a complex reaction pathway involving multiple proton-electron transfers and stringent competition from side reactions. Herein, we developed a series of binary CoCu phosphates with precisely tailored Co/Cu ratios to investigate their synergistic catalytic effects. A volcano-shaped relationship exists between the Co/Cu ratio and the electrocatalytic activity, with Co_0.5Cu_1.5(OH)PO₄ exhibiting optimal performance by facilitating electron transfer and enriching active sites. In 1 M nitrate electrolyte at a high current density of 200 mA cm⁻², the Co_0.5Cu_1.5(OH)PO₄ achieves a remarkable Faradaic efficiency (FE) of 99.0% for ammonia, simultaneously delivering a high production rate of 9.18 mg h⁻¹ cm⁻², while maintaining stable performance over continuous electrolysis for more than 200 h. DFT calculations attribute the superior performance to the optimized Co/Cu ratio. Specifically, the Co sites promote water dissociation to ensure a sufficient supply of active hydrogen, while the adjacent Cu sites utilize this hydrogen to drive the deoxygenation and hydrogenation steps. This effective division of labor significantly lowers the reaction energy barrier, thereby enhancing the intrinsic kinetics of the NO₃RR process.

Solution-processed mercury sulfide (HgS) is an attractive near-infrared absorber but is limited by interfacial instability, high defects, and sluggish response.

The Sb₂S₃ interlayer simultaneously forms Sb–O bonds with fluorine-doped tin oxide (FTO) substrates and Sb–S/Hg–S bonds with the HgS layer, thereby reinforcing interfacial adhesion, passivating coordination-unsaturated defect states, and establishing a type-II heterojunction with a strong built-in electric field.

Comprehensive theoretical and experimental analyses demonstrate that these spirofluorene-anthracene hybrids adopt precisely engineered distorted configurations, effectively suppressing detrimental intermolecular π-π stacking in condensed phases.
