Hydrido-coinage-metal clusters: Rational design, synthetic protocols and structural characteristics

Intercluster exchanges leading to hydride-centered bimetallic clusters: a multi-NMR, X-ray crystallographic, and DFT study

“…Although polyhydrido copper clusters stabilized by chalcogenolates have received tremendous attention due to their potential applications in catalysis, electrocatalytic CO2 reduction, hydrogenation, or energy storage, [20][21][22][23] well-characterized bimetallic hydride clusters of group 11 metals remain scarce partly due to the lack of reliable, convenient synthetic methodologies. [24][25][26] Importantly, the method adopted in this report is significantly different from a recent development by Tsukuda and his co-workers on the subject of hydride-mediated cluster growth involving coinage metals. [27][28]…”

Copper-hydride nanoclusters with enhanced stability by N-heterocyclic carbenes

“…Nevertheless, there remains some key issues in this research area: intrinsic instability, sensitivity towards air, limited surface modifiers, and rareness of superstructures, etc. [20].…”

On the Roles of Electron Transfer in Catalysis by Nanoclusters and Nanoparticles

“…Pioneered by the seminal article from Zhu et al in 2008 reporting the correct crystal structure of Au 25 (SCH 2 Ph) 18 , [16] this key nanocluster family has then attracted considerable attention with a lot of valuable work during the last decade (Figure 1). [16][17][18][19][20][21][22][23][24][25][26][27][28][29] The gold, silver and mixed gold-silver NCs are the most frequent precisely defined NCs, eventually blended with (most often) Pd or Pt atoms, and their size ranges from less than 10 units to more than hundred metal atoms and even occasionally several hundred atoms. [18][19][20][21][22][23][24][25][26][27][28] This NC family with precisely defined structures fortunately contains many examples of efficient catalysts for a large number of reactions.…”

[20,[29][30][31][32][33][34][35][36][37] Therefore, it has recently been possible to establish a relationship between the structure and the catalytic activity of these nanoclusters, insofar as the precise structural change or its absence can be followed by physicochemical techniques along the catalytic reaction, which provides understanding of the catalytic mechanism, a feature of great interest.…”
