Fig. 5: Optimal conditions for synthesizing uniform NCs composed of Ag, Pt, Pd, or Rh.
From: Critical roles of metal–ligand complexes in the controlled synthesis of various metal nanoclusters
a–e UV–vis absorption spectra of homogeneous (p-MBA)-protected Ag NCs (color: burgundy), MHA-protected Ag NCs (color: light gray), MHA-protected Pt (color: sky blue), Pd (color: auburn), and Rh NCs (color: light red), respectively. Dashed lines in a, b indicate the evidence of Ag44(p-MBA)30 NCs and Ag25(MHA)18 NCs, respectively. Dashed lines in (c–e) indicate the evidence of quasi-molecular properties of ultrasmall Pt, Pd, and Rh NPs, respectively. Schematic representations of metal–thiol interaction are described above the UV-vis absorption spectra. The colors of all atoms except for those of metal are identical with those in Fig. 2f-j (Ag: silver, Pt: gray, Pd: auburn, Rh: red). f–j Representative Cs-TEM images of homogeneous (p-MBA)-protected Ag NCs, MHA-protected Ag NCs, MHA-protected Pt, Pd, and Rh NCs, respectively.
