Abstract

original image

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 electrocatalytic reduction of H2O2. The ability to tune the shape offers insight into structure–functionality relationships.
