Bi/trinuclear Pt1,2Cu cluster assembly from isolated metal atoms†
Abstract
We report a facile strategy for synthesizing uniform heterometallic bi/tri-atom clusters starting from mono-metallic atoms in the liquid phase. Specifically, Pt1,2Cu bi/tri-atoms are prepared by reducing CuCl2 at preformed Pt1 atoms with ethanol inside a PDMS-PEG protective layer. The metal atoms in the Pt1,2Cu clusters are in reduced chemical states.
