Area of Science:

• Inorganic synthesis and materials science
• Nanomaterials preparation
• Surface chemistry

Background:

• Precise synthesis of monodisperse nanomaterials is crucial.
• Galvanic exchange often leads to unpredictable structural changes and polydisperse mixtures.

Purpose of the Study:

• To report and rationalize the absolute templating of group 11 clusters via galvanic exchange.
• To demonstrate complete metal exchange within a template across the coinage metal family.
• To provide a molecular model for understanding CO2 reduction on coinage metal surfaces.

Main Methods:

• Utilizing ambiphilic carbenes for enhanced stability.
• Employing galvanic exchange for metal templating.
• Investigating group 11 clusters (copper, silver, gold).

Main Results:

• Achieved absolute templating and complete metal exchange in group 11 clusters.
• Demonstrated predictable synthesis of monodisperse nanomaterials.
• Established a molecular model for CO2 reduction at M(111) surfaces.

Conclusions:
