Accounts of Chemical Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

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

Breaking the Activity-and-Selectivity Seesaw while Enhancing Heat Management via the Lattice Effect of a Single-Atom Alloy

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

When single-atom catalysts are oriented toward practical applications, in addition to balancing the seesaw between activity and selectivity, capability of thermal management also merits attention. Herein, we proposed a facility approach that, based on active Pd state single atom, tunes guest Cu size simultaneously enhance effect d-electron domination heat transfer behavior microregions. Along with an order magnitude increase, more delocalized electrons were generated transferred isolated sites, d band center shifting from 1.438 1.052 eV, closer Fermi level. Simultaneously, long-range ordered lattices much favorable for transferring situ thermally phonons diffusivity surging 12.36 103.49 mm2/s. The optimized Pd1Cu-SAA catalyst exhibited state-of-the-art performance acetylene hydrogenation, achieving full conversion at 140 °C, 95.3% selectivity good stability test period.
