Shape control of Pd-based nanocrystalsvia quasi-solid-state reactions

Abstract

We demonstrated here a quasi-solid-state method for the shape-controlled growth of Pd-based nanocrystals. Tiny amount of solvent is needed to form clusters which can aggregate and then evolve into nanocrystals with different morphologies. It is proposed that the shape-controlled growth processes proceed primarily by the aggregation of the clusters and the subsequent interparticle growth via solid-state self-focusing process.
