Abstract Owing to the specific electronic-redistribution and spatial proximity, diatomic catalysts (DACs) have been identified as principal interest for efficient photoconversion of CO 2 into C H 4 . However, predominant bottom-up strategy DACs synthesis has critically constrained development highly ordered due random distribution heteronuclear atoms, which hinders optimization catalytic performance exploration actual reaction mechanism. Here, an up-bottom ion-cutting architecture is proposed fabricate well-defined DACs, superior proximity CuAu diatomics (DAs) decorated TiO (CuAu-DAs-TiO ) successfully constructed compact heteroatomic spacing (2-3 Å). profoundly low C-C coupling energy barrier CuAu-DAs-TiO , a considerable production with sustainability achieved. Our discovery inspires novel fabrication motivate distinct deduction heteroatom synergistically

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.

Precisely engineering point defects holds promise for the development of state-of-the-art photocatalysts CO2 conversion. This study demonstrates controllable creation nitrogen vacancies (VNs) in centers heptazine rings graphitic carbon nitrides (g-C3N4) via a photochemical-assisted etching strategy. Spectroscopic analyses and theoretical simulations elucidate photochemical process to hydrogenate situated at center g-C3N4 ring then release an ammonia molecule, accompanied by photooxidation sacrificial agents. The catalyst with optimal VNs concentration achieves CO generation rate 35.2 μmol g–1 h–1 nearly 100% selectivity, comparable performance reported materials. remarkably improved photoactivity is due adjustments electronic structures midgap states delocalized π electron cloud created 12-membered surrounding VN, which maximizes light-harvesting efficiencies suppresses recombination photogenerated electrons holes. also activates neighboring catalytic reduce energy barrier reduction. work provides good design concept regulate activity defects.
