Abstract:

Single-atom and dual-atom catalysts (SACs/DACs) have attracted significant interest owing to their maximized atom utilization efficiency and distinctive synergistic properties. Nevertheless, the fabrication of highly efficient and stable SACs/DACs continues to present considerable challenges, largely due to elevated surface energy and the complexity of achieving precise coordination environments and spatial distribution of metallic sites. Effective regulation of chemical bonding between metal centers and supporting matrices is crucial to suppress aggregation tendencies. Carbon nitride (g-C3N4) has gained prominence as a robust scaffold for immobilizing SACs and DACs, attributed to its well-defined electronic configuration, notable chemical stability, and customizable surface characteristics. A dynamic electronic interplay is observed: metal species tailor the electronic properties of g-C3N4, while the support reciprocally modulates the catalytic behavior of metal active sites. This review comprehensively outlines recent progress in g-C3N4-based SACs and DACs, with focused discussion on synthetic methodologies, reaction mechanisms, and applications in greenhouse gas transformation and photosynthetic organic synthesis. Furthermore, the article emphasizes emerging trends in advanced characterization, precision synthesis, and the elucidation of bidirectional metal-support interactions, offering insightful directions for subsequent research in the field.
