Single-Atom-Kernelled Nanocluster Catalyst

Nano Letters, 2022
To propose the concept of single-atom-kernelled nanocluster, we synthesized a Pd-based trimetal nanocluster with a single-Ag atom-kernel for the first time by introducing some steric hindrance factors and employing a joint alloying strategy that combines the coreduction with an antigalvanic reduction (AGR).

Techniques for the characterization of single atom catalysts

RSC Advances, 2022
In this paper, eight methods for identifying single atom catalysts are reviewed. Two of them can directly observe the existence of single atoms, while other methods can provide corresponding evidence of the existence of single atoms.
