Abstract
Translation of nanomaterials from spherical to other shapes has demonstrated property and activity enhancement for applications ranging from optics to catalysis. Unfortunately, synthetic techniques for the controlled production of shaped nanomaterials, which can employ harsh conditions, remains challenging. In contrast, the fabrication of nanostructures using peptides has achieved the generation of functionally active materials using bio-conditions; however, these methods are typically limited to spherical materials. By merging these techniques, the biomimetic/ambient production of functional, shaped nanostructures may be achieved. Here we present the fabrication of non-spherical Pd nanostructures prepared using a peptide template. By controlling the Pd: peptide ratio, the production of at least three different Pd morphologies is possible: nanoparticles, short linear nanoribbons, and nanoparticle networks. Furthermore, all of the materials are active for Stille C-coupling catalysis using aqueous and room temperature conditions at low Pd concentrations. The results suggest that both the zerovalent Pd materials and the ligand surface structure modulate the reactivity, which may be exploitable for optimal functionality.
