ConspectusDual-atom catalysts (DACs), featuring two catalytic sites in close proximity, have emerged as a new frontier energy-related catalysis. Compared with single-atom (SACs), DACs more space to optimize the performance by changing dual-atom and their coordination environments. Through adjusting compositions environments of metal DACs, it is possible finely tune electronic geometric properties active centers, then synergistic effects for facilitating substrates activation intermediates stabilization can be strengthened or optimized, consequently tailoring diverse reaction pathways achieving various challenging reactions. The most important yet task studies precise synthesis which crucial understand relationship between structure at atomic level. In cases, were synthesized via pyrolysis mixture salts organic ligands, metals are randomly distributed was difficult control M···M distance (M = ion) uniform dispersion DACs. Hence, developing innovative strategies definite structures high-efficiency urgently needed.In this Account, we tentatively summarize applications conversion small molecules such H2O, CO2, so on. Focusing on three types been put forward systematically introduced. Based strategies, resulting high purity synergistically activating converting concurrently discussed, including cleavage C-C bonds, reduction CO2 Attempts made explain why these functions much higher than what SACs achieved. Efforts revealing influences dual-metal site types, separations dual metals, geometry configurations environments, well ligand performance. Emphasis has placed analysis structure-reactivity mechanism molecular Finally, perspectives current challenges future development forward. We anticipate believe that Account will provide profound insights into structurally defined give
