ConspectusRecent decades have witnessed the rapid development of catalytic science, especially after Taylor and Armstrong proposed notion "active site" in 1925. By optimizing reaction paths reducing activation energies reactions, catalysts appear more than 90% chemical production involving homogeneous catalysis, heterogeneous enzyme catalysis. Because 100% efficiency active atom utilization adjustable microenvironment metal centers, single-atom (SACs) shine various fields for enhancing rate, conversion, selectivity reactions. Nevertheless, a solo site determines fixed adsorption mode, intermediates from multistep reactions linking with are related to each other. For specific reaction, it is almost impossible optimally adjust every intermediate on simultaneously. This phenomenon termed scaling relationship limit (SRL) an unavoidable obstacle pure SACs.Dual-atom (DACs), perfectly inheriting advantages SACs, can exhibit better performance simple SACs thus gradually gained researchers' attention. Depending dual-metal structure, sites (DMSs) DACs be divided into two separated heterometal sites, linked homometal sites. Two prescribe distance between electron interaction. Currently, origins summarized following three points: (1) electronic effect, which only one center serves as other plays regulatory role; (2) synergistic centers separately catalyze different core steps improve together; (3) offering additional changes structures break SRL based SACs. Among origins, structure upon DMSs most effective technologies boost property basis To date, few contributions focused catalysis environments, including O2 reduction evolution H2 CO2 N2 conversion reactions.In this Account, summary recent progress regarding will presented.

Abstract Designing well‐defined interfacial chemical bond bridges is an effective strategy to optimize the catalytic activity of metal–organic frameworks (MOFs), but it remains challenging. Herein, a facile in situ growth reported for synthesis tightly connected 2D/2D heterostructures by coupling MXene with CoBDC nanosheets. The multifunctional nanosheets high conductivity and ideal hydrophilicity as bridging carriers can ensure structural stability sufficient exposure active sites. Moreover, Co–O–Ti formed at interface effectively triggers charge transfer modulates electronic structure Co‐active site, which enhances reaction kinetics. As result, optimized CoBDC/MXene exhibits superior hydrogen evolution (HER) low overpotentials 29, 41, 76 mV 10 mA cm −2 alkaline, acidic, neutral electrolytes, respectively, comparable commercial Pt/C. Theoretical calculation demonstrates that bridging‐induced electron redistribution optimizes free energy water dissociation adsorption, resulting improved evolution. This study not only provides novel electrocatalyst efficient HER all pH conditions also opens up new avenue designing highly systems.
