“…33 They first synthesized and analyzed Au 25 (PET) 18 , confirming the purity of NCs. Subsequently, the Au 25 (PET) 18 NCs were successfully loaded on sulfur-doped graphene via a facilitated mixing method. Compared to those loading on bare graphene, Au 25 @S-G was no observed trend of aggregation, which was attributed to the bond between sulfur and the Au atom.…”

“…The success in synthesizing a series of Au n (SR) m NCs with different sizes provides an excellent chance to explore the size-dependent catalytic activity at an unprecedented atomic level. [44][45]53,54] As shown in Figure 1, Jin and co-workers classified the Au NCs into three distinct states: metallic NCs with a core size larger than 2.3 nm (> Au 333 ), transition NCs with a diameter of 2.3-1.7 nm (Au 333 ∼ Au 144 ), and nonmetallic NCs with a core size smaller than 1.7 nm (< Au 144 ). [40,52,55] They found that the Au NCs in the transition regime exhibited excellent catalytic activity in both CO oxidation and electrocatalytic alcohol oxidation compared with metallic and nonmetallic NCs.…”

The unclear structures and polydispersity of metal nanoparticles (NPs) seriously hamper the identification of the active sites and the construction of structure‐reactivity relationships. Fortunately, ligand‐protected metal nanoclusters (NCs) with atomically precise structures and monodispersity have become an ideal candidate for understanding the well‐defined correlations between structure and catalytic property at an atomic level. The programmable kernel structures of atomically precise metal NCs provide a fantastic chance to modulate their size, shape, atomic arrangement, and electron state by the precise modulating of the number, type, and location of metal atoms. Thus, the special focus of this review highlights the most recent process in tailoring the catalytic activity and selectivity over metal NCs by precisely controlling their kernel structures. This review is expected to shed light on the in‐depth understanding of metal NCs’ kernel structures and reactivity relationships.

“…Therefore, in this section, we describe the use of Au n (SR) m NCs to enhance the functionality of various electrode reactions. [90,[258][259][260][261][262][263] These reactions comprise the water-splitting reactions (hydrogen evolution reaction [HER] and oxygen evolution reaction [OER]; Section 6.1), cathode reactions in fuel cells (oxygen reduction reaction [ORR]; Section 6.2), and the CO 2 reduction reaction (CO 2 RR; Section 6.3).…”

Atomically precise thiolate‐protected gold nanoclusters: Current status of designability of the structure and physicochemical properties

et al. 2022

Thiolate (SR)‐protected gold nanoclusters (Aun(SR)m NCs) are a rare type of material capable of simultaneously exhibiting multiple physicochemical properties well‐suited to specific applications, including photoluminescence, thermocatalysis, electrocatalysis, photocatalysis, magnetism, and optical activity. Over the past several decades, there has been tremendous progress in our understanding of the structure and physicochemical properties of Aun(SR)m NCs, resulting in the ability to fine‐tune the characteristics of these materials. It is therefore helpful to examine the extent to which the properties of Aun(SR)m and related metal NCs can now be adjusted based on design. This review presents representative examples of previous studies concerning the geometry, electronic structure, luminescence properties, catalysis, magnetism and optical activity of Aun(SR)m and related metal NCs and discusses the current status of the designability of these NCs to impart specific structural and physicochemical characteristics. This information is expected to accelerate the fabrication of highly functional materials based on Aun(SR)m and related metal NCs.
