Journal ArticleDOI
Enhancement in Aerobic Alcohol Oxidation Catalysis of Au25 Clusters by Single Pd Atom Doping
Songhai Xie,Hironori Tsunoyama,Wataru Kurashige,Yuichi Negishi,Tatsuya Tsukuda,Tatsuya Tsukuda +5 more
TL;DR: Au25 and Pd1Au24 clusters on multiwalled carbon nanotubes were developed via adsorption of Au25(SC12H25)18, Pd 1Au 24(SC 12H25), followed by calcination.
Journal ArticleDOI
A Critical Size for Emergence of Nonbulk Electronic and Geometric Structures in Dodecanethiolate-Protected Au Clusters
Yuichi Negishi,Tafu Nakazaki,Sami Malola,Shinjiro Takano,Yoshiki Niihori,Wataru Kurashige,Seiji Yamazoe,Seiji Yamazoe,Tatsuya Tsukuda,Tatsuya Tsukuda,Hannu Häkkinen +10 more
TL;DR: Low-temperature optical absorption spectroscopy, powder X-ray diffractometry, and density functional theory (DFT) calculations revealed that the Au cores of Au144(SC12)60 and smaller clusters have molecular-like electronic structures and non-fcc geometric structures, whereas the structures of the Au core of larger clusters resemble those of the bulk gold.
Journal ArticleDOI
Isolation, structure, and stability of a dodecanethiolate-protected Pd1Au24 cluster
TL;DR: Experiments on the stability of the cluster showed that Pd(1)@Au(24)(SC(12)H(25))(18) is more stable against degradation in solution and laser dissociation than Au(25)(SC (12) H(25)(18), which indicates that the doping of a central atom is a powerful method to increase the stability beyond the Au( 25)(SR)(18) cluster.
Journal ArticleDOI
Alloy Clusters: Precise Synthesis and Mixing Effects
TL;DR: The results revealed that the effects of substitution of each element can be superimposed on the cluster by combining multiple elemental substitutions at different sites, which is expected to lead to clear design guidelines for developing new functional nanomaterials.
Journal ArticleDOI
Precise synthesis, functionalization and application of thiolate-protected gold clusters
TL;DR: Aun(SR)m has received significant attention as new functional nanomaterials because they exhibit size-specific physical and chemical properties that are not seen in bulk gold.
