Platinum nanocrystals with a fine control of the
crystal domain size in the range 1.0−2.2 nm are produced by
tuning the NaOH concentration during the UV-induced reduction
of H2PtCl6 in surfactant-free alkaline ethylene glycol. The colloidal
solutions obtained are characterized by transmission electron
microscopy and pair distribution function analysis, allowing
analysis of both atomic and nanoscale structures. The obtained
nanoparticles exhibit a face-centered cubic crystal structure even
for the smallest nanoparticles, and the cubic unit cell parameter is
significantly reduced with decreasing crystallite size. It is further
demonstrated how the “UV-approach” can be used to achieve
spatial control of the nucleation and growth of the platinum
nanocrystals, which is not possible by thermal reduction.
