Manipulating the architecture of Pd@Pt nanostructures through metal-selective capping agent interactions

Abstract

Pluronic F127 and NaBr were used during co-reduction of Pd and Pt precursors to achieve octopodal and dendritic Pd@Pt nanoparticles selectively through preferential capping interactions. Our findings demonstrate that two capping agents can be used to independently manipulate the growth regimes of metals in the synthesis of bimetallic nanostructures.
