Summary
Stable copper nanoclusters (Cu-NCs) with near-infrared (NIR) emission were synthesized. These bimetallic Cu/Pd nanoclusters exhibit high photoluminescence quantum yield and catalytic activity.
Area of Science:
- Materials Science
- Nanotechnology
- Catalysis
Background:
- Developing stable copper nanoclusters (Cu-NCs) with near-infrared (NIR) emission for catalysis is challenging.
- Atomically precise nanoclusters offer unique properties but require tailored synthesis.
Purpose of the Study:
- To synthesize a novel bimetallic copper-palladium nanocluster (Cu/Pd NC) with NIR emission.
- To investigate its luminescent properties and catalytic activity.
Main Methods:
- Synthesis of an atomically precise bimetallic Cu/Pd NC (Cu16Pd1).
- Single-crystal X-ray crystallographic analysis.
- Photoluminescence quantum yield (PLQY) measurements.
- Catalytic reduction of 4-nitrophenol.
Main Results:
- Successfully synthesized Cu16Pd1 with a defined structure.
- Achieved strong NIR emission (λem > 800 nm) with the highest PLQY among Cu NCs/alloys.
- Demonstrated catalytic activity in the reduction of 4-nitrophenol.
- Attributed NIR emission to supramolecular interactions.
Conclusions:
- This work presents a novel method for synthesizing Cu/Pd NCs.
- The bimetallic Cu16Pd1 is a promising NIR luminescent material and catalyst.
- Highlights the potential of less-studied Cu/Pd NCs in nanotechnology.
