摘要：

(Figure Presented) Star performance: The shape and surface structure of star-shaped gold nanoparticles (NPs) bounded by (331) and vicinal high-index facets, now synthesized for the first time, can be tuned by varying the water content in the deep eutetic solvent. The results confirm that star-shaped Au NPs exhibit superior activity for electro-catalytic reduction of H 2O2. The ability to tune the shape offers insight into structure-functionality relationships. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
