abstract = {Truly spherical silver nanoparticles are of great
importance for fundamental studies including plasmonic
applications, but their direct synthesis in aqueous media is
not feasible. Using the commonly employed copper-based
etching processes, an isotropic plasmonic response can be
achieved by etching well-defined silver nanocubes. Whilst
spherical-like shape is typically prevailing in such
processes, we established that there is a preferential
growth toward silver rhombicuboctahedra, which is the
thermodynamically most stable product of this synthesis. The
rhombicuboctahedral morphology is further evidenced by
comprehensive characterization with small-angle X-ray
scattering in combination with transmission electron
microscopy (TEM) tomography and high-resolution TEM. We also
elucidate the complete reaction mechanism based on UV–vis
kinetic studies, and the postulated mechanism can also be
extended to all copper-based etching processes},
