Hydride-doped Ag17Cu10 nanoclusters as high-performance electrocatalysts for CO2 reduction

Unraveling the transformative pathways of Au-NHC and Au-alkynyl complexes and bridging the gap between molecular and nanoscale gold systems

“…With their distinctive chemical and catalytic properties, gold compounds have been the subject of extensive research in recent decades. 1–70 Research in this field employs either well-defined gold complexes 2,12,52–57,59–70 or gold particles ranging from subnanometer to macroscale with a well/poorly defined structure, 1,3–11,14,24,28–37,39,45,49 each demonstrating unique catalytic behavior. 1–70…”

“…1–7 As a result, gold has emerged as a catalyst of choice for numerous processes, which include but are not limited to the hydrochlorination of acetylene, 1,3 the oxidation of alcohols 3,6–8 and aldehydes, 3 selective hydrogenation, 3,4,6,7 propylene epoxidation, 4,8,49 and C–C bond formation, 2,3,32 among others. 1–42,49,50 Despite the widespread industrial use of heterogeneous gold catalysts, the precise nature of the active gold species in these catalysts remains a subject of ongoing exploration (Fig. 1A).…”

“…4,7,8,37 Various gold complexes and nanoparticles are now easily accessible from readily available sources. 1–70 The distinct advantage of this developed method lies in its sequential approach, allowing the precise procurement of specific gold forms. 1–8…”

“…Atomically precise tuning of interfacial structures has been described for the development of materials with defined functional properties. 14–21 To address the topic of the gap between heterogeneous catalysis and organometallic catalysis, Zheng and co-workers 14 synthesized atomically precise gold nanocatalysts, which demonstrated synergistic action of the gold metallic core with the surface organometallic motifs to enhance the catalysis. Highly stable and recyclable gold-based heterogeneous catalysts with low loadings were reported (up to 0.002 mol%).…”
