Size and composition control of Pt–In nanoparticles prepared by seed-mediated growth using bimetallic seeds
A two-step method has been developed for precise size and composition control of
bimetallic Pt–In nanoparticles. Very small (1.62 nm) PtIn seed nanoparticles with 1: 1 metal
ratio were prepared in the absence of capping agents followed by growth of Pt on their
surface in the presence of oleyl amine as reducing and stabilizing agent. Nanoparticles with
bulk compositions of Pt4In, Pt3In, and Pt2In could be synthesized with average diameter
smaller than 3 nm. TEM, EDX, and XPS provided evidence for homogeneous growth without …
