摘要
Multipod Pt nanocrystals with good uniformity are synthesized using a Pt-binding peptide as the capping agent. The pod length can be tuned by varying peptide concentrations. With high electrochemical surface areas, these nanocrystals can potentially be used as catalysts in electrocatalytic applications. [GRAPHICS] .
