Synthesis And Surface Modification Of Azide Decorated Silver Nanoclusters, Alexander H. Stöckli
Synthesis And Surface Modification Of Azide Decorated Silver Nanoclusters, Alexander H. Stöckli
Electronic Thesis and Dissertation Repository
In nanocluster research, easy modification of the cluster surface while maintaining the cluster core remains a key challenge. Herein we report the synthesis, structure, and properties of four targeted Ag20 nanoclusters (NCs) with surface azide moieties, two of which have 8 azide moieties, [CO3@Ag20(StBu)10(m-N3-C6H4COO)8(DMF)4] and [CO3@Ag20(StBu)10(p-N3-C6H4COO)8(DMF)4], and two of which have 6 azide moieties, [CO3@Ag20(S …

Design And Surface Modification Of Noble Metal-Based Nanocatalysts, Xuchun Wang
Electronic Thesis and Dissertation Repository
This thesis investigates approaches to modifying the surface structure of noble metal-based nanocatalysts. Noble metal-based nanocatalysts, such as Pt and Pd, play a significant role in heterogeneous catalysis due to their capabilities in activating the cleavage or formation of chemical bonds, but still suffer from the high-cost issue and unsatisfied catalytic performance due to too strong or too weak adsorption of intermediates. Considering the surface specificity of heterogeneous catalysis, Bi, a cheap metal, was used to modify the surface of Pt- and Pd-based nanocatalysts. This thesis aims to unveil the role of Bi in improving their catalytic performance from both …
