Facile synthesis of Pd@Pt core–shell nanocubes with low Pt content via direct seed-mediated growth and their enhanced activity for formic acid oxidation†
Abstract
Pd@Pt core–shell nanocubes with a partially covered Pt shell on the Pd nanocubes were synthesized by a direct seed-mediated growth method without a washing process. The FAO activity of Pd@Pt 0.4 at% was 4.3 times and 2.2 times higher than that of Pd cubes and commercial Pt/C, respectively.
