Abstract: Doped nanoparticles (especially bimetal doped nanoparticles) have attracted extensive interest not only for fundamental scientific research but also for application purposes. However, their indefinite composition (structure) and broad distribution hinder an insightful understanding of the interaction between these invasive metals in bimetal doped nanoparticles. Fortunately, atom-precise bimetal doped ultrasmall nanoparticles (nanoclusters) provide opportunities to obtain such insights. However, atom-precise tr… Show more

“…The metal exchange reaction also enables synthesis of alloy clusters composed of metal elements with very different redox potentials, and can replace a larger number of heteroatoms than when using the simultaneous reduction method . Using this type of exchange reaction, alloy clusters such as Au 25− x Ag x (SR) 18 ( x =1–8), Au 25− x Cu x (SR) 18 ( x =1–9), Au 24 Cd(SR) 18 , Au 24 Hg(SR) 18 , Au 24− x Ag x Cd(SR) 18 ( x =2–6), Au 24− x Ag x Hg(SR) 18 ( x =1–8), Ag 25− x Au x (SR) 18 ( x =1,2), Ag 24− x Au x Pt(SR) 18 ( x =1, 2, 4–9), and Au 38− x Ag x (SR) 24 ( x =1–11) have been synthesized to date.…”

“…If we simultaneously substitute some of the Au atoms in Au 25 (SR) 18 with multiple elements, it might be possible to further modulate the resulting electronic/geometric structures and physical/chemical properties of the clusters. However, only a few examples of synthesis of 25‐atom clusters that contain three or more elements have been reported ,,. Therefore, little is known regarding the influence of substitution by multiple elements on the electronic/geometric structure and physical/chemical properties of Au 25 (SR) 18 ,,.…”

“… Due to the luminescence and synergy effect, they are valuable for biolabeling and catalysis . However, the catalytic reaction types are limited to styrene oxidation,, reduction, C−C coupling, hydrolysis,, photocatalysis which usually occurs under more ambient condition attracts less attention. Au 25 − NCs are privileged for their variable valence state (−1, 0, +1), which endow them with a unique electron‐transfer capability to catalyze organic reactions .…”
