Abstract
Here we report a facile synthesis of Pt-on-Pd bimetallic nanodendrites with a Pd interior and dendritic Pt exterior. The developed route rationally utilizes the spontaneous separation of the depositions of Pd and Pt, which endows direct formation of Pt-on-Pd nanodendrites. This is a truly simple and unique process that is quite different from the traditional seed-mediated growth strategy. Fine-tuning of the Pt and Pd ratios afforded Pt-on-Pd nanodendrites with superior electrocatalytic activity in comparison with commercial Pt electrocatalysts.Keywords
