From crude nanocluster mixtures to single species

The unique optical and catalytic properties of atomically precise gold nanoclusters make them highly promising candidates for advanced photovoltaic, catalytic and sensing applications. Since these properties strongly depend on the exact nanocluster size, separation techniques are required to produce monodisperse cluster species from synthesized mixtures. In a joint research project, the sustainable and scalable fractionation of crude gold nanocluster mixtures into single species is demonstrated using anion exchange chromatography.

Furthermore, the groups of the PIs Kaspereit and Peukert successfully apply alternate pumping chromatography for the isolation and purification of single nanocluster species in their joint paper published in Separations.
